Finite-Impulse-Response Modeling of Voltage Instrument Transformers Applicable for Fast Front Transients Simulations
Authors: Dadić Martin , Župan Tomislav , Kolar Gabrijel
Published: June 2022

This paper presents a method for Finite-Impulse-Response (FIR) modeling of voltage instrument transformers. The method is based on Wiener filtering and measurement of the transformer response in the frequency domain using a low frequency network analyzer. The proposed method allows, through digital filtering operation, an accurate simulation of the transformer response to transient excitation. Furthermore, the proposed approach to the modeling of the system function allows unequal spacing of the frequency samples. The linearity of the transformer is analyzed applying the Fourier analysis and different waveforms of the primary voltage, and methods for the model order selection, based on the generalized information criterion, are discussed and applied. The theoretical analysis is confirmed with measurements in time domain, using the recurrent surge generator.

Published: June 2022

The static var compensator (SVC) is a device which is designed to compensate reactive power, increase voltage stability and to reduce voltage fluctuations. Thyristor controlled reactors (TCRs) are composed of reactors in series with bidirectional pair of thyristors. Current through reactors can be continuously controlled by changing the firing angle of thyristor valves, thus

the inductive power can be easily controlled. Typical applications of TCRs in AC systems are voltage stabilization and temporary overvoltage reduction, stability improvement, damping of power oscillations and load balancing. In this paper, harmonic performance analysis of SVC equipped with TCRs is presented. SVCs utilizing TCRs generate harmonic currents and therefore it is necessary to determine the effect of harmonics generated by the SVC on the power system and its elements. This includes interaction of the SVC with the system, the SVC performance under balanced and unbalanced operating conditions and finally, evaluation of countermeasures such as installation of harmonic filters. In order to carry out these analysis, it is necessary to determine harmonic characteristics of the network at the point of SVC connection, existing levels of harmonics, and to know appropriate standards regarding acceptable harmonic levels in the power system. Since harmonic distortions in the system are caused by the interaction between SVC and the system, all system contingencies which may affect system’s frequency response should be evaluated. Detailed power system model should be considered to make sure that parallel resonance points of system do not directly coincide with characteristic harmonics from the SVC. Harmonics generated by SVCs are largely dependent on the operating point within the SVC characteristic. A conservative approach is to use the maximum values of harmonics generated within the spectrum irrespective of the operating point. The results of harmonic performance analysis are important for appropriate design of SVC. Harmonic performance analysis related to SVC application which are presented in this paper include the determination of: frequency response of the transmission network impedance required for the specification and design of filters; the effects of SVC generated harmonics on the power system; the overall filter requirements and countermeasures to reduce harmonics to acceptable levels.
Streamlining the Decision- Making Process on Tubular Rigid Busbar Selection During the Planning / Designing Stage by Utilizing 3D Substation BIM Design Software
Authors: Foškulo A. , Kokoruš M.
Published: June 2022

For Utilities, each substation is regarded as an asset. Managing of assets is one of domains of Asset Management including Life Cycle Costing (LCC) as a decision-making criterion. However, LCC as a decision-making criterion should be applied on an entire substation taking into account all of the potential cost influences for the purpose of achieving of an effective substation management. Asset management as a decision-making process should be observed within a larger context and should be more focused on risk management, as all real decisions include an element of risk due to present uncertainties. Two promising avenues are explored in regards to more comprehensive and rigorous up-front planning through usage of Information Technology (IT). While up-front planning falls under the domain of Lean philosophy, Building Information Modeling (BIM) falls under the category of agile decision-support tools. Utilization of both is explored from a perspective of design-uncertainties under both product and process design. Standard specifications and standard designs are another form of applied Lean Philosophy that reduces design-uncertainty and variability. However, a range of technical solutions stemming out of the standardization can be quite wide. Customization involves specification and design of new / innovative designs with wide range of technical solutions as well. Due to external pressures focused on shortening of the project delivery time, there is a need for a faster project time throughput. This is reflected in the form of a requirement for more rapid engineering decision-making and faster decision cycles. Streamlining of a decision-making process related to the engineering is all about engineers’ awareness of the situation from the project level perspective coupled with utilization of decision-support tools for creation and reuse of knowledge. Plan – Do – Study – Orient (PDSO) cycle is a decision-making model that supports creation and reusability of knowledge along with providing an explanation in regards to the time dimension relating to decision-making, and as such is presented in this paper. The rigid busbar system design is an iterative process influenced by many factors, defined either as design variables or design constraints. As rigid busbars are gaining more popularity for both greenfield and brownfield investments, the rigid busbar system design is explored from a perspective of decision-making streamlining. The case of the rigid busbar system design of El Chaparral project in El Salvador is given.

Published: June 2022

The present numerical study is an attempt to better understand the effect of the aspect ratio (AR) on the velocity field characteristics of the fully-developed turbulent flow in a straight open channel by contrasting a very low and very high aspect ratio cases (AR = 1 and 12). The AR is defined as the ratio of the width of the channel in a plane normal to the flow direction, to the flow depth. The bulk velocity and water depth considered in this study are 0.75 m/s and 30 mm, respectively, which yield a Reynolds number of ReH = 22,500. The transient three-dimensional Navier-Stokes equations were numerically solved using a finite-volume approach with improved-delayed detached-eddy simulation (IDDES) turbulence model. The results revealed that the normalized components of the normal stresses by the turbulent kinetic energy k are constant over most of the velocity field, although k varies in magnitude throughout the velocity field in both AR cases. In addition, the results also revealed a strong anisotropic flow which justifies the formation of secondary currents as a means for transporting the kinetic energy. The results also reveal that both vertical and transverse components of the normal stresses are correlated to the side-recirculation zone (SRZ) and bottom-recirculation zone (BRZ), respectively, which highlights the role of the mean recirculation zones (BRZ & SRZ) in the re-distribution of the turbulent kinetic energy k in the velocity field.

Published: June 2022

The component of an impeller in stirred tank plays an important role in the mixing process for a wide range of industries. The present study conducted the analysis of impeller design specifically on the number of blades to investigate the flow performance in the stirred tank. The analysis was also performed to identify the location of the particle flow dead zone at the bottom of the tank. The grid development and fluid flow study were accomplished using the CFD simulation method via the Ansys Fluent software package. The impeller design with the arrangement of 3,4 and 5 blades number was involved in this study. The rotational speed of the blade was set constant at 90 rpm. The flow characteristic at the vertical position of a tank at 0.01, 0.1, 0.2 and 0.3 m has been investigated. The general governing equation and solution approach used in this simulation were also presented in this paper. The results showed that 5 blades impeller produced a broader region of high-velocity magnitude distribution compared to the 3 and 4 blades. Hence, 5 blades impeller also relatively produced a higher distribution of velocity magnitude compared to the 3 and 4 blades impeller, typically in the upper region of the tank. However, the effect of a number of blades seemed not significant in the region close to the rotating impeller.

We observed near-Sun comet 323P/SOHO for the first time using ground and space telescopes. In late 2020 December, the object was recovered at Subaru showing no cometary features on its way to perihelion. However, in our postperihelion observations, it developed a long narrow tail mimicking a disintegrated comet. The ejecta, composed of at least millimeter-sized dust with power-law size distribution index 3.2 ± 0.2, was impulsively produced shortly after the perihelion passage, during which ≳0.1%–10% of the nucleus mass was shed due to excessive thermal stress and rotational disruption. Two fragments of ∼20 m in radius (assuming a geometric albedo of 0.15) were seen in Hubble Space Telescope observations from early 2021 March. The nucleus, with an effective radius of 86 ± 3 m (the same albedo assumed) and an aspect ratio of ∼0.7, has a rotation period of 0.522 hr, which is the shortest for known comets in the solar system and implies cohesive strength ≳10–100 Pa in the interior. The color of the object was freakish and changed temporally in a never-before-seen manner. Using our astrometry, we found a strong nongravitational effect following a heliocentric dependency of

Published: June 2022

Efficient radiation at second and/or higher harmonics of Ωce has been suggested to circumvent the escaping difficulty of the electron cyclotron maser emission mechanism when it is applied to solar radio bursts, such as spikes. In our earlier study, we developed a three-step numerical scheme to connect the dynamics of energetic electrons within a large-scale coronal loop structure with the microscale kinetic instability energized by the obtained nonthermal velocity distribution and found that direct and efficient harmonic X-mode (X2 for short) emission can be achieved due to the strip-like features of the distribution. That study only considered the radiation from the loop top at a specific time. Here we present the emission properties along the loop at different locations and timings. We found that, in accordance with our earlier results, few to several strip-like features can appear in all cases, and the first two strips play the major role in exciting X2 and Z (i.e., the slow extraordinary mode) that propagate quasi-perpendicularly. For the four sections along the loop, significant excitation of X2 is observed from the upper two sections, and the strongest emission is from the top section. In addition, significant excitation of Z is observed for all loop sections, while there is no significant emission of the fundamental X mode. The study provides new insight into coherent maser emission along the coronal loop structure during solar flares.

Authors: Siregar Jelita , Ihsan Riyadh
Published: June 2022

BACKGROUND: Coronavirus disease-2019 (COVID-19) has various symptoms ranging from mild to critical. Hypercoagulation state is often observed in severe and critical COVID-19. Both coagulation and inflammation are interrelated and amplifying each other, with protein C and antithrombin (AT) III as two important mediators.
OBJECTIVE: To determine the association between protein C and AT III levels with the severity of COVID-19 symptoms.
METHODS: This analytical study was conducted at Haji Adam Malik Hospital from April to July 2021. Subjects were obtained by consecutive sampling method. Inclusion criteria were patients with confirmed COVID-19 using RT-PCR and willing to participate. Subjects were divided into 2 groups: mild-moderate and severe-critical symptom groups. Demographic and blood sample were obtained from each subject. Blood samples underwent examination for leukocyte, thrombocyte, PT, aPTT, protein C, and AT III.
RESULTS: A total of 50 patients were obtained with female domination (58%) and mean age of 41.44 (SD 20.90) years. Most subjects (86%) were in mild-moderate symptom group. There were significant differences in the level of protein C and AT III in both group (p= 0.029 and 0.034, respectively). Using the cut-off values for protein C of 5.36 ng/mL and AT III of 45.6%, subjects who had mediators level below the value tend to develop severe and critical symptoms compared to their counterparts (OR= 5.769 and 6.458, respectively).
CONCLUSION: Protein C and AT III are associated with severity of COVID-19 symptoms. Lower protein C and AT III levels increase the risk for developing severe and critical symptoms.

Published: June 2022

Introduction: Psoriasis vulgaris is a chronic skin disease which is characterized by recurrent scales on skin. The global prevalence of this disease has increased in ten years. Plumbagin is an active compound in the P. zeylanica Linn. Some recent studies revealed that P. zeylanica Linn extracts have the antiproliferative activity, which is used for treatment of some human diseases. The aim of this study was to investigated the effect of Chloroform extract of P. zeylanica Linn roots (CEP) on epidermal thickness of Imiquimod-induced psoriatic mice.

Methods: This was a post-test only control group design. A total of 42 male BALB/c mice was divided into six groups. Mice in treatment groups orally received 25, 50, and 100 mg/kg body weight CEP, respectively while positive control orally received 1 mg/kg body weight Methotrexate for seven days. Evaluation of epidermal thickness based on histological changes, serum IL-23 level by ELISA, and Cyclin-dependent kinase 2, Cyclin A, and Caspase-3 expressions by immunohistochemistry.

Results: Administrations of CEP decreased the epidermal thickness of psoriatic plaques in all treatment groups (p = 0.002, 0.003, and 0.016 respectively) compared to negative control but it did not reduce the serum IL-23 level.  The expressions of CDK2 and Cyclin A reduced in T2 and T3 groups and the expression of Caspase-3 increased was only in T3 group.

Conclusion: Chloroform extract of P. zeylanica Linn roots administrations reduce the epidermal thickness of Imiquimod-induced psoriatic mice by inhibition of keratinocyte cell cycle and induction of Caspase-3 expression.
Updating the list of flower-visiting bees, hoverflies and wasps in the central atolls of Maldives, with notes on land-use effects

Maldives islands host a unique biodiversity, but their integrity is threatened by climate change and impacting land-uses (e.g. cemented or agricultural areas). As pollinators provide key services for the ecosystems and for the inhabitants, it is crucial to know which pollinators occur in the islands, to characterise their genetic identity and to understand which plants they visit and the size of the human impact. Given that no significant faunistic surveys of Hymenoptera have been published for the country in more than 100 years and that Syrphidae were only partly investigated, we sampled islands in the central part of the Maldives country (Faafu and Daahlu atolls) and hand-netted flower-visiting bees, wasps and hoverflies (Hymenoptera: Anthophila, Crabronidae, Sphecidae, Vespidae, Scoliidae and Diptera: Syrphidae). Overall, we found 21 species; 76.4% of the collected specimens were Anthophila (bees), 12.7% belonged to several families of wasps and 10.8% of individuals were Syrphidae. It seems that one third of species are new for the Maldives, based on the published literature. Human land-uses seem to shape the local pollinator fauna since the assemblages of bees, wasps and hoverflies from urbanised and agricultural islands differed from those in resort and natural ones. These pollinators visited 30 plant species in total, although some invasive plants hosted the highest number of flower visitor species. Biogeographically, this pollinating fauna is mostly shared with Sri Lanka and India. Genetically, the used marker hinted for a unique fauna in relation to the rest of the distribution ranges in most cases, although generally within the level of intraspecific genetic variation. This study significantly contributes to increasing the knowledge on the pollinator diversity and genetic identity in Maldives islands also considering the important implications for the islands' land-use and the role of invasive plants. This study will be pivotal for future pollination studies and biodiversity conservation efforts in the region.

Hier phare du tiers-monde, la diplomatie algérienne connaît une éclipse depuis la fin des années 1980. En dépit des efforts des débuts de la présidence Bouteflika, Alger s'est marginalisée face aux désordres de la région : Sahara occidental, printemps arabes, instabilité tunisienne, anarchie libyenne, déstabilisation du Sahel. L'Algérie amorce un réengagement régional mais, au-delà, le rapprochement vis-à-vis des États-Unis et de l'Union européenne reste ambigu, et la carte chinoise ambivalente.

On compterait autour de 400 000 naissances de mères de moins de 15 ans chaque année dans le monde dans les années 2010, soit un taux de fécondité de 13 naissances par an pour 10 000 filles de 10-14 ans. Plus de la moitié surviennent en Afrique subsaharienne où on observe 40 naissances annuelles pour 10 000 filles de 10-14 ans. Le taux de fécondité entre 10 et 14 ans a été divisé par environ six dans le monde depuis le début des années 1970. Dans les pays du Sud, une majorité de ces naissances ont lieu au sein d’unions (mariage ou cohabitation sans mariage).
Evaluation of dietary inclusion of black soldier fly (Hermetia illucens) larvae on fish production performance: a meta-analysis

Published: June 2022

Fishmeal, as one of the main protein sources, has become scarce and expensive. This conventional protein source is no longer considered sustainable. As an alternative, black soldier fly (BSF) is a popular non-conventional protein source that has been tested in the formulation of aquafeed to replace fishmeal due to its nutritional value, reasonably low price, and large abundance. Nevertheless, evidence on the BSF supplementation varied among species. This meta-analysis examined the influence of replacing fishmeal with BSF on the performance of fish species by using 47 published papers targeting 23 different species. The results revealed that, overall, BSF inclusion had no significant effect on survival rate (SR) and feed conversion ratio (FCR). The magnitude effect on specific growth rate (SGR) and weight gain (WG) was species-dependent; it increased SGR and WG of omnivores but decreased (P<0.01) when fed to carnivores and herbivores. Meta-regression analysis indicated a negative linear relationship of FCR on carnivore (P<0.05; R2=0.61) and omnivore (P<0.05; R2=0.15). In addition, principal component analysis confirmed that although most species showed an increasing trend in response to dietary BSF, FCR decreased on a few species (Anabas testudineus and Acipenser baerii) which belong to omnivores. In conclusion, BSF meal can be a partial substitute for fishmeal in the formulation of only some specific species no more than 30%. Special notice should be considered on carnivore and herbivore species because utilisation of BSF in species might compromise their performance.
Creepy crawlies or beauty queens? The effect of type of insect on the evaluation of foods containing insects
Authors: Adamczyk D. , Modlinska K. , Maison D. , Goncikowska K. , Ekström S.S. , Pisula W.
Published: June 2022

Rich in digestible protein, insects are more and more widely considered to be ‘the food of the future’ and a good substitute for meat. However, the willingness to ingest them depends largely on the consumers’ perception of insects. To understand the specificity of insects among other animals, their characteristics as a potential food source, and to examine what makes some insects more acceptable as food than others, we conducted two complementary studies (qualitative and experimental). The qualitative study (18 individual in-depth interviews) allowed us to identify the dimensions that determine the perception of insects as potentially edible and inedible. In the experimental study (n=437), we examined the potential of three different types of insects (larvae, ants, crickets) as food ingredients. Pictures of four versions of the same product (Bolognese sauce) were presented to the respondents – three containing insects and one without insects (control condition). The results showed that foods containing insects scored lower on each dimension. Furthermore, we observed a different impact of various insects on product evaluation: products containing crickets were evaluated higher than those with larvae. In addition, we noted some individual differences in acceptance of insects as food. Respondents with a higher level of food neophobia and a lower level of varietyseeking tendency assessed products containing insects more negatively than participants with higher levels of the latter trait. Our study suggests that the way insect products are advertised makes a considerable difference to the evaluation of those products. Different insects evoke different associations and emotions, which can be reflected in specific associations with a given product.
Sistematización de la información de catastro utilizando POSTGRESQL-POSTGIS. Aplicación al análisis de usos del suelo urbano en Alcalá de Henares, España
Authors: Martín Jiménez Juan Manuel , Rodríguez Espinosa Víctor Manuel
Published: June 2022

El Catastro constituye una fuente de información de gran relevancia en los estudios de ámbito urbano e intraurbano. Ofrece información espacial detallada y precisa, de gran utilidad para apoyar la toma de decisiones en los procesos de planificación y ordenación territoriales. No obstante, en muchas ocasiones su uso se ve limitado por la exigencia de tener conocimiento, más o menos avanzado, de su estructura, contenido, relaciones entre los bancos de datos, etc. y, sobre todo, por ciertas dificultades técnicas en su obtención, tratamiento y adaptación que suponen importantes inversiones de tiempo y recursos.
En este trabajo se propone una metodología específica para una explotación más ágil y eficiente del contenido del Catastro. Basada en consultas a la componente alfanumérica de los datos catastrales, utilizando PostgreSQL-PostGIS, para alimentar la tabla de atributos asociada a la cartografía vectorial de parcelas catastrales, se ha aplicado, a modo de ejemplo, al análisis de los usos del suelo en la ciudad de Alcalá de Henares (Comunidad de Madrid). Los resultados a nivel de parcela permiten identificar la distribución de usos del suelo en la ciudad, la especialización de áreas en unos usos determinados, los principales ejes comerciales, etc. A pesar de las limitaciones, se trata de una propuesta suficientemente concreta, pero a la vez abierta, y aplicable en cualquier área de estudio, lo que podría facilitar y potenciar la utilización de este tipo de información en diversos ámbitos del análisis urbano, en los que se precise de un elevado nivel de detalle de la información espacial.

This study aimed to extract and physical-chemically characterize Terminalia catappa L. kernel oil from purple (CR) and yellow (CA) varieties. Physical-chemical parameters, composition of fatty acids, nutritional quality indices, bioactive compounds and antioxidant capacity of both oil varieties were evaluated according to the literature. Both oils presented low levels of acidity and peroxides, besides the predominance of unsaturated fatty acids, ~63% of oleic and ~26% of linoleic acids, which influenced its nutritional indices. The CR oil variety exhibited a higher content in anthocyanin (18.3 ± 1.5 mg·100 g-1), ascorbic acid (68.4 ± 2.02 mg·100 g-1) and total polyphenol contents (152.3 ± 2.4 mg GAE·g-1), and a good antioxidant activity (38.6 ± 2.2 μg TE·g-1) determined by TEAC assay, when compared to the CA oil (p < 0.05). Therefore, the results confirm the importance of T. catappa as a lipid source for human consumption to be used in the development of food products.

Bovine milk is one of the most complete foods that exist. During the last decades, milk FA have shown to improve human health due to the reduction in risk of cardiovascular disease and related pathologies. The aim of this study was to evaluate the feasibility of near infrared spectroscopy (NIRS) reflectance analysis to predict the nutritional value, fatty acid (FA) composition, and health index of fresh milk from dairy cows of pastoral systems. The prediction of Atherogenicity and Thrombogenicity indexes, along with other FA ratios in fresh milk samples by NIRS were precise and accurate. In addition, the calibration model obtained by NIRS provides an opportunity for the routine quantification of milk’s healthy FA such as omega-3 and conjugated linoleic acid (CLA), with applications in the dairy industry for food labeling, and at the farm level for management of the dairy cow’s diet.

People like to do bird watching but to identify bird species they need help of Zoological Science. Bird watching gives health benefits which we get by enjoying nature. Species identification is a challenging task which may result in many different labels. Sometimes even experts may disagree on species. It is both difficult of humans and computers that hit the limit of visual abilities. Hence, to help the bird spectator, we have developed deep learning based algorithms using the concept of image processing that help in identifying bird species. It will recognize the input image by comparing the model with a trained model and then predict the bird species. All the details of the bird will be displayed as an output. Also, it will help us to create dataset if any image captured or uploaded by user is missing in dataset then user can add that image to dataset.

Ce travail propose d’analyser l’origine d’une partie des manuscrits des poèmes composés par les prisonniers politiques pendant la dernière dictature argentine, entre 1976 et 1983. Il s’agit plus particulièrement de nous intéresser aux lieux, aux supports et aux pratiques de l’écriture poétique qui s’est développée de façon surprenante et inespérée malgré les conditions éminemment précaires auxquelles étaient exposés les auteurs. Nous n’allons pas réaliser l’analyse littéraire des poèmes mais plutôt démontrer, d’une part, que les lieux de détention ont été, en même temps et paradoxalement, des lieux de création. D’autre part, il s’agira de voir que, malgré les obstacles pensés et tendus par les autorités pénitentiaires, divers supports et pratiques ont surgi pour permettre la diffusion et circulation de cette poésie « inattendue ».
EFFECTIVE SEMANTIC FEATURES TO IMPROVE RETRIEVAL OF LUNG NODULES IN CT SCAN IMAGES
Authors: Alizade Mehdi , Foruzan Amir Hossein
Published: June 2022

Successful treatment of a patient depends on the accurate determination of the disease type. The advent of big data facilitates the retrieving of medical images and helps physicians in reliable diagnoses using content-based medical image retrieval systems (CBMIR). They consist of a feature extraction module and a distance metric. The extracted textural or deep-based features identify different types of diseases. In the proposed retrieval algorithm, we use the gray level cooccurrence matrix as the common textural characteristics and integrate them with semantic attributes. The semantic features are the geometric characteristics of the tumor that a radiologist employ to distinguish between benign and malignant tumors. These high-level attributes include the Euler number, margin smoothness, and the aspect ratio of the lesion’s size. We used the Minkowski distance measure for computing the similarity of images and applied the proposed algorithm to 200 CT-scan data containing lung lesions obtained from the LIDC database. The types of lesions were benign and malignant. Employing an ablation study, we proved the effectiveness of the semantic feature. The precision of the retrieval results is 93% which is promising compared to recent studies. In the future, we plan to define other kinds of semantic attributes to distinguish stages 1–5 of lung tumors as well.

Published: June 2022

The thermal and mechanical effects of human tissues and physics that governs biological processes has been developed by applying fundamental engineering principles in the investigation of numerous heat and mass transfer applications in biology and medicine. An incompressible magnetohydrodynamic nanofluid flow passing over a stretched surface along with the effect of viscous dissipation is analyzed numerically. In order to create a nonlinear transformed model in terms of ordinary differential equations, suitable similarity transformations are used and solved by employing a Mathematica algorithm. Furthermore, a minimal case comparison standard has been provided to validate the current methodology. The machine learning method is built through very important parameters. Simulations and machine learning approaches could work together to reveal new and fortunate prospects in computational science and engineering problems. The performance of the parameters in terms of heat and mass transfer is presented with an aid of graph to demonstrate the applicability of the current model.

Published: June 2022

Face-recognition systems must be capable of identifying patient faces in an uncontrollable situation. Facial detection is a distinct problem from facial recognition in that it needs to report the location and size of all of the faces in a given image, which is not possible with face recognition. There are numerous changes in the images of the same face, which makes it a difficult problem to solve because of their general likeness in appearance. Face recognition is a very difficult procedure to do in an uncontrolled environment, since the lighting and angle of the face, as well as the quality of the image to be recognized, all have a considerable influence on the outcome of the process. This chapter provides information regarding the various face recognition machine learning models. The performance of the models is compared on the basis of values derived for FAR, FRR, TSR, and ERR.

Analyzing the Evolution of Interdisciplinary Areas
Authors: Lee Won Sang
Published: June 2022

Recently, various new areas of research have been of great interest to researchers. As these areas are highly based on academic and industrial needs, it is necessary to examine the change and evolution in research. This study proposed a framework for identifying emerging areas and their evolution. The proposed framework suggests that latent Dirichlet allocation is applied to identify emerging topics and their networks in such interdisciplinary areas. The simulation for empirical network analysis was then applied to the identified topic networks to terminate continuous evolution. The proposed framework is applied to a smart city, which is one of the most interdisciplinary and fast-evolving areas. These findings indicate that the evolution of smart transportation and smart grids is likely to be the focus. The findings also indicate that newly emerging research may lack openness and diversity. This study contributes to further investigate research trends and planning research strategies for new and interdisciplinary areas.
Psychiatrists on social media – new frontiers: Four years into my YouTube channel, “Mental Health Round Table”
Authors: Sirisena K. D. S.
Published: June 2022

Over the last decade or so the expanding landscape of mental health education and engagement with the public has extended into the frontiers of social media (SM). We can no longer remain deaf, dumb or mute about the impact of social media on how individuals become informed about mental health issues. If trained professionals are not familiar with the use of social media, or if they are not willing to use this medium, then the space would be invariably be filled by others, often untrained individuals, some with varying motivations. There is an urgent need to equip mental health professionals to facilitate effective and appropriate use of social media, to enable them to become better communicators in mental health.
Communities, child and adolescent development and mental Health
Authors: Attygalle U. R.
Published: June 2022

Our communities are changing, and we need to look at its impact on our children and adolescents. How families interact with their children and the attachment experiences thus created, are important factors that have an effect on child and adolescent development. The quality of these experiences are in turn influenced by broader community level factors. These need to be taken into consideration in the prevention of mental health issues and in managing psychiatric disorders. Both formal community level interventions, as well as informal promotion of positive community influences are needed.

Authors: Fernando G. K. S. , Fernando W. K. T. R. , De Silva M. D. K.
Published: June 2022

Background: Undiagnosed anxiety and depression are obstacles for the effective treatment of post-surgical dysphagia. The prevalence and associations between postsurgical dysphagia and anxiety and depression are poorly studied areas in Sri Lanka. 
Aims: This study aimed to determine the proportion of anxiety and depression among patients with dysphagia following oral, oral maxillofacial (OMF), and neck surgeries, and to identify the associations between the severity and stage of dysphagia, and the occurrence of anxiety and depression.
Methods: A cross-sectional study was conducted among 95 participants with post-operative dysphagia following oral, OMF and neck surgeries, at four tertiary care hospitals. The Hospital Anxiety and Depression Scale, oral-motor and cranial nerve examination, the 3ml water swallow test, cervical auscultation and the Dysphagia Severity Rating Scale were used for data collection.
Results: The majority of the participants (52%) presented with dysphagia in the pharyngeal phase, and 51% presented with severe dysphagia. Among the participants, 52% screened positive for depression and 39% for anxiety, while 37% and 47% showed borderline levels of depression and anxiety respectively. There was a statistically significant association between increasing severity of dysphagia and increasing levels of anxiety.
Conclusions: This study reflects that there is a high psychological burden among patients with dysphagia following oral, OMF, and neck surgeries. This highlights the need for the incorporation of interdisciplinary treatment strategies, as undiagnosed anxiety and depression are likely to impact negatively on the rehabilitation and management of patients with dysphagia.

The thematic system in the construction of Arabic Sufism communities and Islamic identity
Authors: Anis Muhammad Y. , Nababan Mangatur , Santosa Riyadi , Masrukhi Mohammad
Published: June 2022

This research aims to investigate the thematic system (theme and rheme) of Arabic texts, especially Arabic Sufi texts related to al-Hikam aphorisms. Thematic structure is defined as the set of options relating to ‘information structure’, the linguistic representation of extralinguistic experience and how a Sufi constructs an information structure in al-Hikam aphorisms. In this case, the extralinguistic experience is focused on the Arabic Sufi communities (Tarekat Syadziliyah community). The first problem of this research, about thematic system in al-Hikam aphorism related to Arabic Sufi communities and Islamic identities, is elaborated comprehensively. The elaboration process can be classified into a number of thematic systems such as (1) unmarked topical, (2) marked topical, (3) interpersonal and (4) textual. The thematic analysis becomes the base foundation to elaborate the construction of Arabic Sufi communities and Islamic identities. A thematic model shows how language users in Arabic Sufi communities encode language from their mental picture of reality. By capturing the al-Hikam aphorism through the thematic system, it can be concluded that communication is pivotal in making Islamic Sufi identities.Contribution: Contextually, this research contributes to the study of cross-language and cross-culture. Language as a reflection of a certain culture can be seen both in terms of the product and the translation process.
