Odnos zborskih aktivnosti i dobrobiti pjevača amatera
Authors: Škojo Tihana
Published: November 2021

Unatoč aktualnim pojavnostima u društvu koje sustavno utječu na smanjenje slobodnoga vremena kod svih društvenih skupina, zborsko je pjevanje zadržalo svoju bogatu tradiciju i mjesto najzastupljenije slobodne aktivnosti u kojoj pojedinci uspješno iznalaze načine da zadovolje svoju potrebu za aktivnošću, socijalizacijom, da kvalitetno zadovolje zanimanje za glazbu i glazbeno stvaralaštvo te da se dodatno afirmiraju u društvu. Na temelju dosadašnjih istraživanja ukazujemo na odnos glazbenih aktivnosti i dobrobiti pojedinca, povezanost pozitivnih emocija s pjevanjem u zboru, što se očituje u promjeni fiziološkoga statusa pjevača te na razvoj glazbenih vještina i poboljšanje psihofizičkoga stanja pjevača. Vodeći se iskustvima iz ranijih svjetskih istraživanja, a radi utvrđivanja odnosa aktivnosti zborskoga pjevanja i dobrobiti pjevača amatera provedeno je istraživanje u kojemu se ispitala duljina pjevačkog staža, zadovoljstvo životom, doprinos pjevanja subjektivnom osjećaju dobrobiti te percipirana procjena fizičke, emocionalne, socijalne i duhovne dobrobiti. Dobiveni rezultati potvrđuju da pjevanje u zboru pruža brojna osobna poboljšanja kod pjevača. Pjevači procjenjuju da je najsnažnija dobrobit od zborskog pjevanja povezana s emocionalnim, zatim socijalnim pa fizičkim i najmanje s područjem duhovne dobrobiti. Zborsko pjevanje, osim primarne umjetničke funkcije, pridonosi emocionalnoj, društvenoj i fizičkoj dobrobiti kao važnom cilju slobodnih aktivnosti i života uopće.

Authors: Karmokar Sanju , Hasan Kamrul , Khan Ayatullah , Kabir Kazi Humayun
Published: November 2021

If stakeholders, service providers, and social systems adopt sustainable consumption behavior and regulate the production and consumption cycle, they may be facilitated to accomplish sustainable development with environmental and socioeconomic advantages. However, the purpose of this study was to look at the driving forces that influence consumer behavior in Bangladesh in terms of sustainable consumption. A quantitative survey was conducted among 384 participants aged 18 years and having minimum higher secondary educational qualifications. The data were collected from Khulna City Corporation of Bangladesh through a structured interview schedule using the convenience sampling technique. The results reported that environmental concern of the participants was found to be the top-ranked driving force and perceived environmental knowledge of the participants was the lowliest ranked driving force behind the consumers’ behavior towards sustainable consumption. Alongside, attitude towards eco-friendly products, perceived consumer effectiveness and sustainable consumption intention were found to be the second, third and fourth ranked driving forces, respectively. The authors hope and anticipate that the findings of this paper will give critical information to relevant authorities and policymakers in order to develop market research and management policies and strategies.
Why Perpetrators and Innocent Victims are Sometimes Harshly judged? Belief in a Just World and Other Situational Determinants
Authors: Mikani Mehdi , Rafiee Parisa
Published: November 2021

Although Belief in a Just World (BJW) has positive influences on well-being, the attempts to maintain these beliefs may give rise to awry judgments in contexts of harm. In a scenario-based study, we examined the associations of general belief in a just world (GBJW) with BJW maintenance strategies, including victim blaming, victim derogation, perpetrator demonization, and compensation. We hypothesized that because these harsh judgments about victims and offenders along with compensation are used as defensive mechanisms against threats to BJW, using a specific strategy depends on the availability of each strategy and the level of a person’s GBJW. Thus, we also tested whether GBJW and situational cues for victim’s respectability and perpetrator’s evilness have interaction effects on various strategies to defend BJW. By manipulating the characteristics of the victim (professor vs. car dealer) and offender (with evilness cues vs. without evilness cues) in a crime scenario, the interaction effects on judgments about victims and perpetrators as well as compensation were investigated. The results indicated that while GBJW interacted with victim’s respectability and perpetrator’s evilness to predict demonization and derogation, there was no three-way interaction and two-way interaction effects between victim’s respectability and perpetrator’s evilness on the four BJW-maintenance strategies. Taken together, our findings highlight the nuanced effects of just world beliefs on how people react to and make sense of violent incidents.

Color in Architecture: Before and After Industry Revolution
Authors: Martosenjoyo Triyatni
Published: November 2021

Color as a visual element cannot be separated from architectural design. The development of knowledge about color involved artists and scientists. In the past, color was always associated with the activities of artists as creators of decorative works using pigments produced by nature. Artists and scientists assume that color occurs due to the influence of light and dark which is homogeneous. This was later refuted by Newton's findings that color is produced by heterogeneous light. Different colors are a result of different refractive indexes. The discovery of artificial colors by Perkin encouraged the industry to create colors not only to produce colors that exist in nature, but also according to the wishes of the user as an individual. The opportunity to use colors according to the needs of individual users then encourages businesses to control colors so that the industry does not suffer losses if the colors of the products they produce do not sell well in the market. They work closely with color forecasters and color designers to determine color trends according to the interests of producers through color cards. This condition is followed by architects who create color schemes based on their own favorite color palette. This article finds out how the development of science positions color in architectural works? The research was conducted with a historical approach and data interpretation methods through a literature review.

Personality differences between sex and sexual orientation group
Authors: Díaz Alice
Published: November 2021

It has been argued that because some biological underpinnings affecting personality occur in a continuum (e.g. hormonal exposure), personality scores in a given population should also occur in a continuum. Personality sex differences have been widely studied but these do not allow to study personality as a continuum. To tackle this limitation, Lippa (2001) suggested using sexual orientation. The Shift and the Inversion Hypotheses have been proposed to predict how the personality scores of homosexual participants would differ from their heterosexual counterparts. However, these efforts have been largely ignored. This study used a large UK sample to compare these hypotheses using personality scores at the facet and domain level. The results suggested that there was evidence for the Shift and the Inversion Hypotheses at the facet level, but these patterns were obscured at domain level where groups tended to cluster according to sexual orientation. Moreover, Neuroticism was often responsible for the largest differences across groups at facet and domain level.
Event-related transcutaneous vagus nerve stimulation modulates behaviour and pupillary responses during an auditory oddball task
Authors: Villani Valerio , Finotti Gianluca , Di Lernia Daniele , Tsakiris Manos , Azevedo Ruben
Published: November 2021

Transcutaneous auricular vagus nerve stimulation (taVNS) is a neuromodulatory technique that is thought to activate the Locus Coeruleus-Noradrenaline (LC-NA) system. Standard taVNS protocols consist of the administration of intermittent or continuous stimulation over long periods. However, there is currently limited understanding of temporal dynamics of taVNS modulation of cognitive processes, as well as its mechanisms of action. We argue that novel stimulation approaches, informed by established theories of the LC-NA system, are needed to further our understanding of the neurocognitive underpinnings of taVNS. In this pre-registered study, we tested whether an “event-related” taVNS protocol can modulate the LC-NA system. In a within-subject design (single session) we delivered brief trains of taVNS (3 seconds) during an auditory oddball paradigm. The taVNS was time-locked to the target stimuli and randomly interleaved with sham stimulation. Response times (RT) and stimuli-driven pupillary diameter (PD) were used as indices of LC-NA activity. Results revealed that active taVNS increased RT to targets, as compared to sham trials. Notably, in line with current theories of LC-NA functioning, taVNS modulation of target-related pupil dilation depended on pre-stimulation PD, an index of tonic LC-NA activity. In particular, active (vs. sham) taVNS was associated with smaller pupil dilation in trials where the baseline PD was small. These results demonstrate, for the first time, the effectiveness of brief event-related taVNS in the modulation of cognitive processes and highlight the importance of using pupil size as an index of tonic and phasic LC-NA activity.
Virtual Reality and Emotion: A 5-Year Systematic Review of Empirical Research (2015-2019)
Authors: Markowitz David Matthew , Bailenson Jeremy
Published: November 2021

The central aim of this chapter is to identify how immersive VR can be used as a tool to inform our understanding of emotion and how emotion operates as a mechanism for VR effects. To accomplish this goal, we conducted a 5-year systematic review of the VR and emotion literature (2015-2019), while also reviewing seminal pieces from outside the 5-year timeframe to provide additional perspective on the more recent work. This decision to start the review in 2015 was purposeful in order to focus our review on recent, not historical trends in VR and emotion research, and to identify empirical studies that are concerned with three types of research: (1) the connection between VR and emotion from a emotion regulation perspective (e.g., mood induction, clinical applications), (2) studies that treat emotions as a mechanism to evaluate social or psychological phenomena, and (3) studies concerned with a deeper understanding of emotions or emotion theory. Our perspective draws on evidence from communication research, psychology, and human-computer interaction to achieve these aims. We ground our investigation in an overview of immersive VR and discuss current debates in emotion research. Finally, we attempt to make connections across fields by drawing on literature since 2015.

Shopping behaviour in response to extreme events is often characterized as “panic buying” which connotes irrationality and loss of control. However, “panic buying” has been criticized for attributing shopping behaviour to people’s alleged psychological frailty while ignoring other psychological and structural factors that might be at play. We report a qualitative exploration of the experiences and understandings of shopping behaviour of members of the public at the onset of the COVID-19 pandemic. Through a thematic analysis of semi-structured interviews with 23 participants we developed three themes. The first theme addresses people’s understandings of “panic buying”. When participants referred to “panic buying” they meant observed product shortages (rather than the underlying psychological processes that can lead to such behaviours), preparedness behaviours, or emotions such as fear and worry. The second theme focuses on the influence of the media and other people’s behaviour in shaping subsequent shopping behaviours. The third theme addresses the meaningful motivations behind increased shopping, which participants described in terms of preparedness; some participants reported increased shopping behaviours as a response to other people stockpiling, to reduce their trips to supermarkets, or to prepare for product shortages and longer stays at home. Overall, despite frequently using the term ‘panic’, the irrationalist connotations of “panic buying” were largely absent from participants’ accounts. Thus, “panic buying” is not a useful concept and should not be used as it constructs expected responses to threat as irrational or pathological. It can also facilitate such behaviours, creating a self-fulfilling prophecy.
Print-and-Play Fabrication
Authors: Tejada Carlos E.
Published: November 2021

In recent years, it has become increasingly accessible to create interactive applications on screen-based devices. Contrary to this ease, and despite their numerous benefits, creating tangible interactive devices is a task reserved for experts, requiring extensive knowledge on electronics, and manual assemblies. While digital fabrication equipment holds promise to alleviate this situation, the majority of research exploring this avenue still present significant barriers for non-experts, and other-domain experts to construct tangible devices, often requiring assembly of electronic circuits and printed parts, prohibitive fabrication pipelines, or intricate calibration of machine learning models. This thesis introduces Print-and-Play Fabrication: a digital fabrication paradigm where tangible interactive devices are printed, rather than assembled. By embedding interior structures inside three-dimensional models that leverage distinct properties of fluid behavior, this thesis presents a variety of techniques to construct tangible devices that can sense, process, and respond to user’s interactions without requiring assembly of parts, circuits, or calibration of machine learning models. Chapter 2 provides an overview of the fabrication of tangible devices literature through the lens of Print-and-Play Fabrication. This chapter highlights the post-print activities required to enable each of the efforts in the literature, and reflects on the status of the field. Chapters 3 and 4 introduce two novel techniques for constructing tangible devices that can sense user’s interactions. AirTouch uses basic principles of fluid behavior to enable the construction of touch-sensing devices, capable of detecting interactions in up to 12 locations, with an accuracy of up to 98%. Blowhole builds on this concept by employing principles of acoustic resonance to construct tangible devices that can detect where they are gently blown on. Blowhole-enabled devices can enable up to seven interactive locations, with an accuracy of up to 98%. Conversely, in Chapter 6 I introduce a technique to encapsulate logic computation into 3D-printed objects. Inspired by concepts from the Cold War era, I embed structures capable of representing basic logic operations using interacting jets of air into three-dimensional models. AirLogic takes the form of a toolkit, enabling non-expert designers to add a variety of input, logic processing, and output mechanisms to three-dimensional models. Continuing, Chapter 5 describes a toolkit for fabricating objects capable of changing their physical shape using pneumatic actuation. MorpheesPlug introduces a design environment, a set of pneumatically actuated widgets, and a control module that, in tandem, enable non[1]experts to construct devices capable of changing their physical shape in order to provide output. Last, I conclude with reflections on the status of Print-and-Play Fabrication, and possible directions for future work.

Published: November 2021

This paper describes the optimization of energy conversion when solar radiation occurs at peak power conditions, namely at 11.00 am to 2.00 pm where the position of the sun is parallel to the layout of the PV Rooftop installation. The panels used are 5 units with the type of polycrystalline with a capacity of 1 panel unit consisting of 250 Wp. The position of the panels installed on the roof of the Andalas University building is based on an angle of 90o degrees with a position of ±255m above sea level. The advantages obtained when placed on the roof of the building are due to the minimal impact of shadow effects and environmental disturbances. Data retrieval using DC current and voltage sensors is then connected to the Arduino Uno microcontroller which is then interfaced in graphic form. Considerations in the installation of PV by reviewing the weather conditions at that time where the conditions were sunny and the air was clean with the aim that the performance when solar radiation entered the solar cells could be produced more optimally. Based on the data obtained at peak power, PV can convert DC power to 972.56 Wp. In the final stage of collecting data recorded on this PC, it can later be used as a reference for installing solar panels for household electricity scales in the West Sumatra region.
The Use of a Modified Script Concordance Test in Clinical Rounds to Foster and Assess Clinical Reasoning Skills
Authors: Tayce Jordan D. , Saunders Ashley B.
Published: November 2021

The development of clinical reasoning skills is a high priority during clinical service, but an unpredictable case load and limited time for formal instruction makes it challenging for faculty to foster and assess students’ individual clinical reasoning skills. We developed an assessment for learning activity that helps students build their clinical reasoning skills based on a modified version of the script concordance test (SCT). To modify the standard SCT, we simplified it by limiting students to a 3-point Likert scale instead of a 5-point scale and added a free-text box for students to provide justification for their answer. Students completed the modified SCT during clinical rounds to prompt a group discussion with the instructor. Student feedback was positive, and the instructor gained valuable insight into the students’ thought process. A modified SCT can be adopted as part of a multimodal approach to teaching on the clinic floor. The purpose of this article is to describe our modifications to the standard SCT and findings from implementation in a clinical rounds setting as a method of formative assessment for learning and developing clinical reasoning skills.

Annotation. Introduction. The implementation of measures to reform the economy as a whole, agrarian reform and, in particular, land relations in agriculture, was one of the factors influencing the change in the structure of the resident population in terms of economic activity and changes in the agricultural labor market. Analysis of the distribution of the population of Ukraine by economic activity indicates a decrease by almost one third of the number of the economically active population in 2019 compared to 2000. There is also a trend towards a decrease in the number of those employed in economic activity. Purpose. The aim of the article is exploration of employment indicators (formal and informal) and unemployment of the rural population in Ukraine and identification of the main trends. Results. It has been established that the employed rural population is less educated and, accordingly, they perform mostly unattractive types of work that do not require high qualifications. It was revealed that workers in rural settlements have fewer job opportunities at their place of residence. In villages, the number of people who are employers is almost half. The biggest problem in rural areas is self-employment or predominantly employment in private households. A sharp increase in the share of unemployed youth who cannot find a job after graduating from educational institutions has been established. The situation with regard to youth employment in the villages of Ukraine is especially difficult. It turned out that 2/3 of workers in rural areas are employed in the informal sector. Moreover, two urban residents of this sector prefer hired labor, in agriculture, on the contrary, self-employed make up 74.0%, that is, they work in a peasant farm for agricultural products. In half of the cases, informal employment is carried out in agriculture. Conclusions. The unemployed urban dweller is more educated and therefore has more advantages over the rural dweller in terms of employment. Unemployed people in cities have more opportunities to choose a job, therefore they are more active when they leave their jobs of their own accord and depend on the seasonality of their work. For 1990-2019 the average number of fulltime agricultural enterprises decreased 12.2 times due to the liquidation of agricultural enterprises. One of the reasons was the denationalization and privatization of enterprises in Ukraine, especially in rural areas, which were not supplemented by effective mechanisms for the employment of people, including by promoting the development of entrepreneurial activity.

To obtain the maximum yield of winter wheat, it is necessary to further optimize the existing cultivation technologies in the direction of their adaptation to changing environmental conditions. One of the areas of adaptation of plants to adverse abiotic factors is the active functioning of the photosynthetic apparatus, which depends on the amount of nutrients introduced. The influence of fertilizer application on the condition of the pigment complex of winter wheat plants in the conditions of the Southern Steppe of Ukraine has been studied. Two varieties of winter wheat were selected for the study: Shestopalivka and Mason. The experiment scheme involved the application of fertilizers at sowing (K0; K12) and foliar treatment with various tank mixtures (urea; urea + magnesium sulfate; urea + magnesium sulfate + potassium monophosphate). The pigment content has been determined by grinding fresh leaves of winter wheat, followed by the addition of a solvent in the form of acetone. Measurements of pigments were performed using a spectrophotometer. According to the research results, it was established that before the foliar treatment the a-chlorophyll content and carotenoids was higher in the plant leaves of the Shestopalivka variety. At the same time, the b-chlorophyll content on the contrary was higher for plants of the Mason variety by 17%, which may be due to the adaptation of plants of this variety to lack of light. On the 3rd day after foliar treatment, a decrease in the pigment content in the plant leaves of all experimental variants has been observed, which was due to the active growth of the photosynthetic surface and a decrease in the total dry matter mass. There was no significant difference between the varieties of the content of photosynthetic pigments in this period. On the 10th day after foliar treatment, an increase in a- and b-chlorophyll content has been observed for both studied varieties, which may be the result of adaptation of the photosynthetic apparatus of winter wheat plants to lighting conditions. Foliar treatment of winter wheat plants with a tank mixture of urea with magnesium sulfate and potassium monophosphate contributed to a further increase in the content of a-chlorophyll by 12-23%, and b-chlorophyll by 5-37% depending on the variety compared to the control. The results of the research testify to the high efficiency of complex application of nitrogen-phosphorus-potassium fertilizers for foliar treatment of winter wheat plants in the BBCH 31 stage, both against the background of pre-sowing application of potassium fertilizers and without it.

The paper presents the methodology of preparation of samples of oilseeds, lettuce, apples for research by chromatographic control of xenobiotics of the following chemical groups of pesticides: benzimidazole derivatives, anilinopyrimidine derivatives, bipyridylium derivatives. The implementation of the following processes is considered: homogenization of the sample, purification of the extract by solid-phase or liquid-liquid extraction, obtaining a plant extract, obtaining an extract of analytes. For fine-grained homogenized samples of sunflower seeds, the optimal ratio of raw material -extragent is 1:20, for pasty homogenized samples of apple fruit - 1:10, for liquid samples of homogenized lettuce - 1: 5. Analysis of the distribution of xenobiotics in the system octane/water, the dipole moment of solvents allowed to determine the extractants that are able to dissolve and remove xenobiotics from raw materials. It was found that a mixture of acetonitrile and methanol (4: 1) should be used to remove benzimidazole derivatives and anilinopyrimidine derivatives, bipyridylium derivatives are best extracted with methanolic trifluoroacetic acid (9.5: 0.5). Quantitative analysis of xenobiotics content in extracts obtained from samples artificially enriched with xenobiotics was performed. The most complete xenobiotics were removed from samples of plant products containing traces of fat. The most difficult process of sample preparation is the process of obtaining sunflower seed extract. The content of xenobiotics in extracts obtained from samples artificially enriched in analytes is influenced by the temperature at which the process takes place and the duration of extraction. Based on the chemical composition of the sample matrix and the list of analytes, the conditions of the variable component of the methodology are proposed: obtaining plant extract under the action of selective solvents, homogenized raw material-solvent with constant stirring of the extraction system at 180-200 rpm, or under the action of ultrasonic vibrations with a frequency of 37 kHz from 4°C to 25°C for 5-25 minutes. The control of the qualitative and quantitative composition of the studied plant extracts and analyte extracts was investigated by the methods of high-performance liquid and gas chromatography (liquid and gas) with mass-selective detectors.
Nuliglucaemia Lucidae: Extreme Deprivation of Blood Glucose as Organic Context for Cancer Treatment with Antimetabolites
Authors: Gratacós E Prieto , Oliver P García , RP Alvarez , MA Redal , I Sosa , M Laguzzi
Published: November 2021

The present report describes our clinical findings regarding the use of high dose intravenous insulin in cancer patients, as a means to deplete the blood compartment of glucose molecules. The purpose of this intervention is to create a favorable physiological state for the competitive inhibition of several rate-limiting enzymes within cancer cells, with structural analogues that behave as antimetabolites. Regardless of their histological origin, virtually all solid tumors reported on to date (February 2020) are found to be hypercaptant in PET-CT scans following the intravenous injection of 2-¹⁸fluoro-deoxy-D-glucose. Most solid tumors display a hypermetabolic phenotype (SUVmax ≥ 3), with marked overexpression of glucose transporters (GLUTs) in the outer membrane of their anaplastic cells subpopulations. The fact that neoplastic cells also overexpress glycolytic, fermentative and glutaminolytic enzymes up to an order of magnitude relative to healthy cells further strengthens the argument for a competitive inhibition with antimetabolites. The rationale for a deep, systemic deprivation of glucose was suggested by classical enzymological work concerning competitive inhibition (the Woods principle), and our group has shown that a metabolic intervention with structural analogues of glucose and pyruvate is strongly enhanced by a systemic suppression of the natural substrates of hexokinase 2 (HK-2) and lactic dehydrogenase isozyme A (LDH-A), followed by the timely introduction of several non- metabolizable analogues. Sustained, deep hypoglycemia (<10mg/dl) under physiological ketosis provides an advantageous context for antitumor treatment with structural analogues of glucose, pyruvate and glutamine. Data provided in this report demonstrates the feasibility and safety of the procedure.
Cytogenetic differences in blood and cancer tissue samples of the same patient group

Published: November 2021

Breast cancer (BC) is the most prevalent malignant disease in females worldwide. Genomic instability in tumor tissue has been associated with tumor progression. These genetic changes may take a variety of forms, including numerical and structural chromosomal abnormalities (CAs), epigenetic changes, and gene expression alterations. Many tumor tissues are made up of genetically different cell populations, and the study of the causes and consequences of this heterogeneity play a central role in cancer research. In this study, CAs in blood and cancer tissues of patients with sporadic BC were examined. Our findings shows that the increase in numerical sex aneuploidy in BC tissues is significantly higher than in blood tissue. These aneuploidy increases in cancer tissues seem to be compatible with the development and increase of cancer, and can play a role in the pathogenesis of cancers. These changes are consistent with early and long-standing exposure to carcinogens, especially estrogens. These findings should clarify our understanding of breast carcinogenesis in breast tissues and promote development of improved methods for risk assessment and BC prevention in women.
Use of Transtracheal Oxygen following Decannulation of Pediatric Tracheostomy
Authors: Chowdhury Ujjwal Kumar
Published: November 2021

Purpose: Uninterrupted sustained oxygenation is paramount in neonates and infants with cyanotic/acyanotic congenital heart diseases (CHD) undergoing closed or open heart surgeries and tracheostomy tube decannulation to avoid hypoxic events. Description: We describe here-in a new device, permitting uninterrupted delivery of oxygen through the tracheostomy stoma, allowing continuation of enteral feeds and suctioning of the endotracheal secretions through the tracheostomy stoma. Evaluation: Eighty-four neonates and infants with a median age of four months (IQR:23 days-9 months) undergoing different closed and open heart surgeries for cyanotic/acyanotic CHD with or without pulmonary arterial hypertension were treated with a device permitting uninterrupted oxygenation following tracheostomy tube decannulation. There were 11 (13.1%) deaths due to multifactorial etiologies, and one was lost to follow-up. Seventy-two children were successfully decannulated using this protocol. At a median follow-up of 166(IQR:82.5-216) months, the actuarial survival was 86.61% (SE±0.04%; 95% CI: 77.1-92.3). Conclusions: Transtracheal oxygenation through the tracheostomy stoma via a thin catheter allows uninterrupted oxygenation following tracheostomy tube decannulation, continuation of enteral feeds, and allows intermittent endotracheal suctioning, thus avoiding post decannulation hypoxic events.

We report a patient in the sixth decade of life with a benign anomalous course and a history of atherosclerotic disease in the right coronary artery with the presence of ischemia. We present a clinical case of infrequent finding of abnormal left coronary artery and obstructive atherosclerotic lesion in the circumflex artery. The authors decided to perform coronary angioplasty on the lesion found. Because it is an infrequent condition, we conducted a literature search in which we focused on the statistical findings, the clinical presentation and detailed the treatment of the patient by means of coronary angioplasty. Despite the difficulty of the case, success was achieved.

Authors: Taghi Sheykhi Mohammad
Published: November 2021

The paper reflects an image of Alzheimer's disorders in Asia as the largest continent of the world. Asia with increasing life expectancy and elderly people is facing Alzheimer's disorders within the emerging aging people leaving behind various issues. Aging in Asia is also in parallel with poverty and health deficiency. Many parts of Asia is getting aged before becoming rich. Spread of Alzheimer's disorders while needing more and additional capital to invest, is in low position. Under such circumstances, the countries of the region need new paradigms and policies to combat the emerging Alzheimer's within the aging cohorts. Aging as a new phase of life needs new strategies to put into effect, to take care of those involved with Alzheimer's disorders. Aging as a new part of life needs more scientific study, and the practice of plans to modify the issue.

Energy/information dissipation and blood flow in human body
Authors: Beraia M. , Beraia G.
Published: November 2021

The amount of work done to displace blood in systemic arteries and capillaries exceeds the work done by the left ventricle. Besides, at the heartbeat, electromagnetic energy dissipates from the heart to the whole human body. For the problem study, the dielectric spectroscopy method was used. Ringer’s, amino acid solution, and heparinized venous blood were affected by the external electromagnetic oscillations (100-65000Hz, 1-8MHz.) in 17 healthy individuals. Correlations were noted between the initial and induced signal forms/frequencies according to the impedance of the system. The electric impulse from the heart initiates an oscillating electric field around the charged cells/particles and an emerging repulsing electromagnetic force, based on the electroacoustic phenomena, promotes the blood flow, in addition to the pulse pressure from the myocardial contraction. Blood conduces mechanical, electromagnetic waves of different frequencies and transmits energy/information to implement the spontaneous chemical processes in the human body.

Published: November 2021

Coronary artery vasospasm (CAV) is an under-recognized cause of ACS in patients with COVID-19. Difference in pathophysiology and management increases the importance of the identification of these patients. We describe the first case of CAV in a patient with COVID-19 in the absence of signs of severe systemic inflammation.
Fulminant Myocarditis: Brief Review
Authors: Amsterdam Ezra A , Majid Muhammad
Published: November 2021

Fulminant myocarditis (FM) is a rare disease characterized by acute hemodynamic impairment and ventricular arrhythmias due to severe myocardial inflammation. It is typically preceded by a viral infection but any of multiple other toxic and infective agents may also be the inciting agent. Diagnosis is based on biomarkers and/or cardiac imaging, but endomyocardial biopsy is the standard test for confirming the diagnosis. FM usually requires therapeutic support of cardiac function and treatment of malignant arrhythmias. Contrary to prior concepts, recent evidence has revealed that patients with FM are more likely to die or need heart transplantation than those with the nonfulminant form of the disease. Early recognition and aggressive management are essential for favorable outcomes.

Published: November 2021

Coronavirus disease 2019 (COVID-19) is defined as illness caused by a novel coronavirus now called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2; formerly called 2019-nCoV), which was first identified as an outbreak in Wuhan City, Hubei Province, China [1]. Cases of multisystem inflammatory syndrome after Covid – 19 infection have been extensively documented in children. CDC reported 27 cases of multisystem inflammatory syndrome in adults (MIS-A) in direct reports through October 2020, as well as various case series and published case reports [2]. Cytokine storm, as a trigger of the progression of HF in patients with COVID-19, has become a novel focus to explore therapies for target populations [3]. In this article, we briefly present a case of a Covid-19 infection associated myocarditis complicated by acute heart failure successfully treated with IVIG.
Development and Evaluation of Learning Modules in Rabbit Production
Authors: Nicolas Honeylet J.
Published: November 2021

ABSTRACT A newly-offered subject in agriculture, rabbit production, necessitated the development of instructional materials. This mixed-method study was conceptualized to develop and evaluate learning modules for the subject, utilizing the ADDIE model of instructional design. Development of ten modules took almost two years, and the first semester of usage was done with flexible learning methods. Student and faculty users assessed the acceptability in terms of objectives, content, organization and usability, and language, while pre-test and post-test scores determined the effectiveness of the modules. Based on the results, the students rated the modules with moderate acceptability, while instructors and professors rated them with high acceptability. The modules were effective in increasing the knowledge of students in both the midterm and final periods. The learning modules may help provide locally-suited learning materials in rabbit production for Philippine tertiary schools, and in disseminating information and awareness on rabbit as a high-potential livestock in the Philippines.
Computational Approaches for Supporting Combination Therapy in the Post-Aducanumab Era in Alzheimer’s Disease
Authors: Geerts Hugo , van der Graaf Piet
Published: November 2021

With the approval of aducanumab on the “Accelerated Approval Pathway” and the recognition of amyloid load as a surrogate marker, new successful therapeutic approaches will be driven by combination therapy as was the case in oncology after the launch of immune checkpoint inhibitors. However, the sheer number of therapeutic combinations substantially complicates the search for optimal combinations. Data-driven approaches based on large databases or electronic health records can identify optimal combinations and often using artificial intelligence or machine learning to crunch through many possible combinations but are limited to the pharmacology of existing marketed drugs and are highly dependent upon the quality of the training sets. Knowledge-driven in silico modeling approaches use multi-scale biophysically realistic models of neuroanatomy, physiology, and pathology and can be personalized with individual patient comedications, disease state, and genotypes to create ‘virtual twin patients’. Such models simulate effects on action potential dynamics of anatomically informed neuronal circuits driving functional clinical readouts. Informed by data-driven approaches this knowledge-driven modeling could systematically and quantitatively simulate all possible target combinations for a maximal synergistic effect on a clinically relevant functional outcome. This approach seamlessly integrates pharmacokinetic modeling of different therapeutic modalities. A crucial requirement to constrain the parameters is the access to preferably anonymized individual patient data from completed clinical trials with various selective compounds. We believe that the combination of data- and knowledge driven modeling could be a game changer to find a cure for this devastating disease that affects the most complex organ of the universe.
