Authors: Syam Dewi Rahmawati , Yosy Deny Salverra , Bakri Achirul , Nova Ria
Published: March 2021

Background Rheumatic heart disease (RHD) causes premature deaths every year worldwide. Low socioeconomic level is considered to be a risk factor facilitating the transmission of airway infections due to Streptococcus pyogenes. Subclinical RHD is a stage of RHD in which heart valve abnormalities have occurred according to the WHO or WHF classification but without any complaints to the subject. Echocardiography is used to screen subclinical RHD in several countries.
Objective To estimate the prevalence, risk factors, and echocardiographic features of subclinical RHD in children.
Methods This cross-sectional study was conducted on 250 elementary school children in Palembang, South Sumatera. We interviewed subject's parents about family characteristics, environment, and history of recurrent sore throat. Subjects underwent anthropometric examination, auscultation, and echocardiography. Diagnosis of RHD was based on World Health Organization (WHO) and World Heart Federation (WHF) criteria.
Results Of 250 subjects, 132 (53.8%) were girls. Subjects’ age range was 5-14 years. The prevalence of subclinical RHD was 8% (95%CI 4.8 to 11.6). Of the 20 subclinical RHD subjects, 15 (75%) met the possible RHD criteria, 5 (25%) met the probable RHD criteria, and none met the definite RHD criteria. Multivariate analysis showed that household crowding (OR 8.135; 95%CI 1.048 TO 63.143; P=0.045), history of recurrent sore throat within the previous 6 months (OR 6,476; 95%CI 1.79 to 23.427; P=0.004) and age > 10 years (OR 3.167, 95%CI 1.184 to 8.471; P=0.022) significantly increased the risk of subclinical RHD.
Conclusion The prevalence of subclinical RHD in elementary school children in Palembang was 8%. For echocardiographic features, most cases met the WHO/WHF possible RHD criteria. Factors significantly associated with the incidence of subclinical RHD are age > 10 years, household crowding, and history of recurrent sore throat in the previous 6 months.

Authors: Jiang Zehui , Zhang Jun , Wang Junyong , Li Junshan , He Meihui , Lu Yuanan
Published: March 2021

Objective
To understand the present status of high blood pressure in Jiangxi adults including the prevalence rate, overall awareness, and hypertension treatment.

Methods
a total of 7,200 adult participants (over 18 years old) lived in Jiangxi were recruited using a stratified sampling method. Blood pressure was measured for all the participants and a questionnaire survey was conducted. A 24-hour urine sample was also collected to understand urine sodium and potassium levels.

Results
Our findings revealed that the measured systolic blood pressure (SBP) and diastolic blood pressure (DBP) were 125.9 mmHg (95% CI, 124.85-126.95) and 79.2 mm Hg (95% CI, 78.15-80.25). The prevalence of hypertension among the enrolled adults was 27.43% (95% CI, 26.38%–28.48%). Among the affected participants, less than 30% of them (95% CI) were aware of their hypertension condition, and only 28.56% (95% CI) were under anti-hypertension medications. The mean salt intake converted from urinary sodium was 10.92±4.07 g and the mean±SD of 24-h urinary sodium and potassium excretion were 185.51±65.44 mmol and 25.98±9.16 mmol, respectively. The high-salt condiments was determined to be the main source of sodium in the region.

Conclusion
Findings from this study form the baseline information to understand the hypertension condition in the region and indicate a possible solution for hypertension prevention through avoiding high-salt condiments.
The Influence of Siblings on Young Children’s Understanding of Fluid Intake
Authors: Williamson Josh , Howells Kristy
Published: March 2021

Background
Children need to drink enough water (1.1-1.3 litres) throughout the day to stay hydrated and for health benefits1. Wellbeing and cognitive function benefits have been identified for children who are hydrated2. Yet there is a dearth of research focusing specifically on children’s perceptions of their own fluid intake levels and who helps support them in ensuring they are drinking enough water, this is a novel area to investigate. Previous research3 identified that 44.2% of young children’s fluid intake were influenced the strongest by a family member. This paper will explore in further detail the influence of siblings on children’s fluid intake, in particular older versus younger siblings.

Methods
130 children (67 girls and 63 boys, of which 45 had a younger sibling (s) and 85 having an elder sibling(s), from 4 primary schools in the South East of England, were questioned between January and April 2019 using an adapted version of Coppinger and Howells’ (2019)4 questionnaire, on their understanding of fluid intake, how much they perceived they drank and who supported them in prompting them to drink. Physical visual representations were used to aid question comprehension and to ensure the questions were appropriate for young children. The data was analysed using SPSS 24.0 using MANOVAs (P < 0.05) to consider statistical variance in gender and older sibling status.

Results
The most significant results were linked to elder siblings influence younger siblings in drinking too little fluids within a school day (F=0.530, p<0.05), whilst those without an elder sibling, thought they drank beyond the daily recommended guidelines and reported they drank over 2 litres. This illustrates that children misunderstand fluid intake recommendations regardless of whether they have an elder sibling or not. Children named adults, both parents and teachers as well as elder siblings as the key influencers of them drinking (F=3.67, p<0.05) and the data indicated that girls were more influenced by siblings than boys, whilst twins were not influenced by each other.

Conclusion
It is concluded that siblings do have an influence on the consumption of water, as siblings act as role models and other siblings follow their habits, therefore the whole family unit is important to ensure that the right fluid intake is consumed. It is recommended that further education, curriculum and community development is needed to continue to support young children’s knowledge and understanding of fluid intake.
Retrato femenino: Metáfora del mapa para la representación de la vida en México
Authors: García-Guerra Gabriela Arhelí
Published: March 2021

El cuerpo femenino en el arte es el espacio en el cual se manifiestan los esquemas de pensamientos sociales. En México, la mujer ha jugado distintos roles que la encasillan, lo cual se ha plasmado pictóricamente en diferentes ocasiones. El presente artículo es el derivado de una investigación doctoral que abarcó obras pictóricas hechas en México del siglo XX-XXI. No obstante, para este texto nos concentramos en obras pertenecientes al siglo XX que muestran el cuerpo de la mujer como territorio o mapa. Nuestro objetivo es reflexionar acerca del retrato, la mujer y la cartografía del ser por medio de un método iconográfico. Se abordan los conceptos de mapa y espacio de acuerdo con distintos creadores y teóricos, para llegar a una reflexión acerca de cómo el cuerpo es el mapa de nuestro ser y particularmente cómo el arquetipo de la mujer mexicana contiene referencias tanto históricas como biográficas.
La música que des-cubre el silencio: Pedagogías decoloniales para la educación musical de personas sordas
Authors: Otero Caicedo Liliana Elizabeth
Published: March 2021

Hemos naturalizado la “limitación” de las personas sordas hasta tal punto que, desde la educación musical, son pocos los cuestionamientos para defender la música como un derecho humano fundamental. Más aún, los fundamentalismos binarios de deficiencia/capacidad, normal/anormal, oyente/sordo, constituyen un horizonte colonial que somete a las personas sordas, anulando su ser-sonoro bajo los presupuestos dominantes de la ideología de la normalidad. Desde las pedagogías decoloniales, se comprende la experiencia musical como una práctica estética-política-pedagógica que debe provocar fracturas en el entendimiento hegemónico de este arte sonoro, posibilitando una descolonización del sonido que devenga en el reconocimiento del capital musical que tiene la comunidad sorda y, así, comprender la diferencia auditiva como la oportunidad de des-cubrir otros mundos musicales que legitimen las posibles destrezas innatas, las experiencias interculturales y los intereses en el campo musical de quienes habitan el silencio.

This article proposes an improved methodology for the development of decision support systems, developed on the basis of a situational scheme for solving behavioral problems by a person. The proposed methodology proposes an approach to solving the problem of decision support based on the ontological model of an organization (business process), containing information about typical situations, their features, options (scenarios) of decisions and indicators for choosing these decisions. An intelligent mechanism for “recognition” of the states of typical situations has been developed on the basis of categorization and the use of the obtained hierarchy of their states and features. A general approach to keeping the ontological model up to date is proposed. The examples of the application of the methodology for the enterprise of the aircraft industry are considered.

Authors: Dizaye Kawa , Othman Zainab
Published: March 2021

Background and Objectives: Miswak is the public name of Salvadora persica, which is beneficial for dental treatments and can thus be used to treat gingivitis. This study compares the therapeutic effects of miswak (S. persica), toothbrush, S. persica mouthwash, and chlorhexidine mouthwash on patients with mild to moderate gingivitis by estimating gingival index and (debris) plaque index. Patients and Methods: The study is a selective sampling, cross-sectional, clinical comparative study of 50 systemically healthy patients in Erbil city. The patients were divided randomly into five groups, with each group having 10 patients. Group 1 used S. persica chewing stick only; group 2 used toothbrush only; group 3 used both S. persica and toothbrush, group 4 used S. persica mouthwash and toothbrush; while group 5 used chlorhexidine mouthwash and tooth-brush. The patients’ mouths were examined, recording clinical indices before and after four weeks from the administration of treatments. Results: There is significant improvement observed between groups 3 and 1 and groups 3 and 2 regarding gingival index. Moreover, there is significant improvement in debris (plaque) index between groups 2 and 3 and groups 2 and 1. Conclusion: The gingival index indicates that using S. persica and toothbrush together is better than using S. persica or toothbrush alone. Meanwhile, the debris index shows that using S. persica alone or using it with toothbrush is more effective than using toothbrush alone. Keywords: Salvadora persica, gingivitis, gingival index, debris index.

Authors: Hanchinal A. M. , N. Patil R. , V. Katti V.
Published: March 2021

The distribution of wall static and stagnation (CP and CPO) pressure coefficient on a flat rectangular element by impinging air jet from the hexagonal orifice is obtained from experimentation. The past research studies helped to identify key parameters such as orifice geometry, jet exit-to-plate-distance (Z/dj), test section inclination (θ), jet Reynold number (Re), lateral distance-to-jet diameter (X/dj), test surface type and geometry, for better and acceptable results. The experimental outcome helps to know the effect of identified key parameters on wall static and stagnation pressure on a rectangular test plate in a confined flow path. The independent nature of wall static pressure is observed for all jet Reynold number (10000 ≤ Re ≤ 50000). Higher pressure coefficient values were observed at lower Z/dj = 1, X/dj = 0 and θ = 0. A significant drop in CP values are seen with the increase in Z/dj, X/dj and θ. The experimental CP and CPO contribution of confined flow are compared against the unconfined flow, around 48% to 58% enhancement is observed when confinement is used. Experimental pressure drop measurements across orifice were made and pressure loss coefficient (PC) for hexagonal orifice of confined and unconfined condition are reported.

Published: March 2021

In this study, an oscillating heat pipe heat exchanger has been used as a heat recovery device in air ductwork, and the characteristics of the thermal performance of the energy-saving were investigated by using a circular and elliptical cross-sectional tubes. An experimental study was conducted by oscillating heat pipe made from copper with an inner diameter of 3.5 mm for the conventional tube, and the major and minor axis of 4.2 and 2.2 mm for the elliptical tube. The working fluid was water with filling ratio of 50% of the total volume. The experimental data implied that the thermal effectiveness and the energy-saving highly affected by the inlet air temperature and velocity. The proposed model of the oscillating heat pipe heat exchanger possessed the effectiveness of 19.5% at 50 ºC and 0.5 m/s, and the potential energy-saving of 1117 W at 50 ºC and 2 m/s. The comparison results between the elliptical and conventional cross-sectional area of oscillating heat pipe heat exchanger indicated that the energy-saving and effectiveness enhanced by the ratio of 18%, and 14%.

Authors: Rosli R. , Mohamed Z. , Priyandoko G.
Published: March 2021

This paper presents a modified intelligent active force control (AFC) control strategy in a semi active seat suspension system. The main actuator studied in this research is the Magneto-rheological (MR) damper. Since a semi-active device like MR damper can only dissipate energy so a modified version of AFC controller is needed. The modified AFC controller main function is to determine the appropriate control force. A Heaviside Step Function (HSF) is used to ensure the MR damper produce the desired damping force according to the control force generated by AFC controller. The phenomenological Bouc-Wen is used to study the effectiveness of the new AFC controller taking into account the dynamic response of the damper. Sinusoidal signals simulated as vibration sources are applied to the seat suspension system to investigate the improvement of ride comfort as well as to ascertain the new AFC controller robustness. Comparison of body acceleration signals from the passive suspension with AFC controller semi active seat suspension system shows up to to 45% improvement to the occupant ride comfort under different vibration intensities.

Published: March 2021

Every year, thousands of people in Malaysia have to be moved out and be relinquished from their homes due to heavy rainfall and poor irrigation system that led to a flood situation especially on monsoon season. Thus, the current study aims to concentrate on the two central aspects of disaster management in the context of flood disaster management in Kuantan, Pahang by the means of a mixed-method approach. The effectiveness of communication mechanisms in the case of floods is assessed with quantitative analysis using descriptive design. On another note, this study also takes a closer look at the underlying logistical framework found in flood disaster contexts and identifies its critical success factors via a qualitative research technique. Using thematic analysis, in-depth semi-structured interviews are analysed to arrive at conclusions regarding the critical success factors. Findings on the effectiveness of disaster communication indicated that the communication between authorities, agencies, non-government organizations and flood victims are still in need of improvement particularly related to emergency updates and increasing community awareness on the right actions for upcoming floods. The study also proved that coordination, communication, knowledge, and preparedness are the critical success factors for humanitarian response in the case of flood management. It is vital to protect the communities from flood disaster; hence, a clear and precise standard operating procedure needs to be in place and must be integrated among all related agencies which will benefit the stakeholders.
Incidence of hyperkalemia during hypertonic saline test for the diagnosis of diabetes insipidus
Authors: Potasso Laura , Refardt Julie , Chifu Irina , Fassnacht Martin , Fenske Wiebke Kristin , Christ-Crain Mirjam
Published: March 2021

Objective

Hyperkalemia has been reported upon different hypertonic saline infusion protocols. Since hypertonic saline test has recently been validated for the differential diagnosis of diabetes insipidus (DI), we aimed to investigate the course of plasma potassium during the test.

Design

We analyzed data of 90 healthy volunteers and 141 patients with polyuria–polydipsia syndrome (PPS) from two prospective studies evaluating the hypertonic saline test. Our primary outcome was the incidence rate of hypertonic saline-induced hyperkalemia > 5 mmol/L.

Methods

Participants received a 250 mL bolus of 3% NaCl solution, followed by 0.15 mL/min/kg body weight continuously infused targeting a plasma sodium level of 150 mmol/L. Blood samples and clinical data were collected every 30 min.

Results

Of the 231 participants, 16% (n = 37/231) developed hyperkalemia. The incidence of hyperkalemia was higher in healthy volunteers and in patients with primary polydipsia (25.6% (n = 23/90) and 9.9% (n = 14/141), respectively), and only occurred in 3.4% (n = 2/59) of patients with diabetes insipidus. Hyperkalemia developed mostly at or after 90-min test duration (81.1%, n => 30/37). Predictors of hyperkalemia (OR (95% CI)) were male sex (2.9 (1.2–7.4), P => 0.02), a plasma potassium at baseline > 3.9 mmol/L (5.2 (1.8–17.3), P => 0.004), normonatremia at 30-min test duration (3.2 (1.2–9.5), P => 0.03), and an increase in potassium levels already at 30-min test duration as compared to baseline (4.5 (1.7–12.3), P => 0.003). Hyperkalemia was transient and resolved spontaneously in all cases.

Conclusion

The hypertonic saline test can lead to hyperkalemia, especially in patients with primary polydipsia who experience a longer test duration. Monitoring potassium levels in these patients is recommended.
Impact of age on survival in radioiodine refractory differentiated thyroid cancer patients
Authors: Saïe C , Wassermann J , Mathy E , Chereau N , Leenhardt L , Tezenas du Montcel S , Buffet C
Published: March 2021

Objective

The objectives of our study were to analyze the influence of age on the survival of patients with RAIR-DTC and to determine their prognostic factors according to age.

Methods

This single-center, retrospective study enrolled 155 patients diagnosed with RAIR-DTC. The primary end point was overall survival (OS) according to different cutoff (45, 55, 65, 75 years). Secondary endpoints were progression free survival (PFS) and prognostic factors in patients under and over 65 years.

Results

Median OS after RAIR diagnosis was 8.2 years (95% IC: 5.3–9.6). There was no difference according to age with a 65 (P = 0.47) and 55 years old cutoff (P = 0.28). Median OS improved significantly before 45 years old (P = 0.0043). After 75 years old, median OS significantly decreased (P = 0.0008). Median PFS was 2.1 years (95% CI: 0.8–3) in patients < 65 years old, and 1 year in patients ≥ 65 years old (95% CI: 0.8–1.55) with no statistical difference (P = 0.22). There was no impact of age on PFS with any cutoff. In both groups, progressive disease despite 131I treatment reduced OS. In patients < 65 years old, an interval of less than 3 years between the initial diagnosis and the diagnosis of RAIR metastatic disease was predictive of poor survival. In patients > 65 years old, the presence of a mediastinum metastasis was a significant factor for mortality (HR: 4.55, 95% CI: 2.27–9.09).

Conclusion

In RAIR-DTC patients, a cut-off age of 65 years old was not a significant predictive factor of survival. Forty-five and 75-years-old cutoff were predictive for OS but not PFS.
The Characters (Χαρακτῆρες) of the Glagolitic Alphabet: New Light on an Old Puzzle
Authors: Mathiesen Robert
Published: March 2021

The article calls attention to a neglected source for the over-all “look and feel” of the Glagolitic alphabet as it was first created by Constantine the Philosopher circa 863 ad. This source is the variant forms of the Greek and other alphabets (including Hebrew and Arabic) that consist of so-called Brillenbuchstabe (otherwise charactères à lunettes or ring-letters). These variant alphabets were employed chiefly for esoteric purposes, including astrological and magical ones. Because of their limited use, they have largely been overlooked in standard handbooks of Greek and Oriental paleography. An interest in such subjects as astrology and magic comports poorly with routine assumptions about the inner lives of Medieval Saints such as Constantine. Relying on the extant primary sources for Constantine’s life, however, the article shows that his education, interests and mystical inclinations make a familiarity with some of these esoteric alphabets virtually certain. Thus it is historically plausible that such alphabets were among the inspirations for the general style, that is, the “look and feel”, of the letters of Constantine’s original glagolitic alphabet. (This article supplements the author’s earlier study from 2014, “A New Reconstruction of the Original Glagolitic Alphabet”.)
The Arabic-Turkish Fragments of the Croatian Latinist Writer Bartul Đurđević in the Polish Anti-Tatar Book Alfurkan Tatarski by Piotr Czyżewski (Wilno, 1616/1617)
Authors: Temchin Sergei
Published: March 2021

The article focuses on the small Oriental texts published in Piotr Czyżewski’s Polish anti-Muslim pamphlet Alfurkan tatarski (Wilno, 1616/1617) directed against the local Tatars of the Grand Duchy of Lithuania. These texts consist of a small Arabic-Turkish prayer and the well-known Ottoman prophecy about “The Red Apple” and the expected victory of Christians over the Turks. The author argues that they go back to the Latin-language editions of the Croatian writer Bartul Đurđević/Bartolomej Georgijević (c. 1506 – c. 1566), who, after his return from a long Ottoman captivity, published several books on the Turkish subjects that were translated into many national European languages and disseminated in different editions throughout Western and Central Europe. These editions often contained samples of Ottoman texts accompanied by a parallel Latin translation and Latin-language interpretations of them, as well as small bilingual dictionaries, thus introducing Islam and the Turkish language to Europe. The article demonstrates the widespread prevalence of both Oriental texts (the Arabic-Turkish prayer and the Ottoman prophecy) in the European printed tradition and the presence of interest in them in the Polish-Lithuanian Commonwealth, evidenced by a manuscript copy of the Ottoman prophecy (late 17th century) and the Polish translation of both texts published in 1548 and 1615.

On the base of obtained results for certain class of analytic functions we calculate asymptotic values of some $n$-widths.

On connection of finite distortion mappings with length distortion in $\mathbb{R}^n$
Authors: Sevostianov Ye.A.
Published: March 2021

The present paper is devoted to the investigations of mappings with finite distortion in $\mathbb{R}^n$, $n \geqslant 2$. In the work it is proved that every open discrete mapping with finite distortion by Iwaniec such that the branch set of $f$ is of measure zero is a mapping with finite length distortion provided that the corresponding outer dilatation satisfies the inequality $K_O (x, f) \leqslant K(x)$ a.e., where $K(x) \in L_{loc}^{n-1}(D)$.

On subgroups that are nearly pronormal
Authors: Chupordia V.A.
Published: March 2021

A subgroup $H$ is called abnormal in the group $G$ if $g \in {<}H, H^g{>}$ for each $g \in G$. A subgroup $H$ of a group $G$ is called a strong selfnormalizer if for all subgroups $K$ such that $H \leqslant K$ the equality $N_K(H) = H$ is true. We obtain the examples of non-abnormal but strong selfnormalizer subgroups.
A note on H-convergence
Authors: Kogut O.P. , Kogut P.I. , Rudyanova T.N.
Published: March 2021

In this paper we study the H-convergence property for the uniformly bounded sequences of square matrices $\left\{ A_{\varepsilon} \in L^{\infty} (D; \mathbb{R}^{n \times n}) \right\}_{\varepsilon > 0}$. We derive the sufficient conditions, which guarantee the coincidence of $H$-limit with the weak-* limit of such sequences in $L^{\infty} (D; \mathbb{R}^{n \times n})$.

“Traditions” from Folklore Studies to Media Product and the Beginnings of Broadcasting in Romania
Authors: Iosif Corina
Published: March 2021

The rhetorical logic of the discourse which is currently building the image of the junction between tradition and nation (and of the concepts thus required) is also due to processing this discourse in the media. That is to say that the connection between media communication and the political instrumentalization of traditions as a domain of national constructs has offered proper soil for shaping the political and ideological narratives based on nation.

The use of some concepts, such as nation, national culture, traditions and folklore in the first decades of the 20th century, and their instrumentalization as radio products, created the premises and particularly the pattern of some specific discursive constructions regarding the nation- state. These were meant to be integrated, embraced and, especially, reproduced on a large scale. Therefore, the discourse focused on national identity – with all its constitutive elements (the state, the language, the history and traditions) – could disseminate a unique hypostasis, shaped under political control, which thus legitimated it. From 1928, the year when the first radio programs were broadcast, until directly after the 1950s, when the recording of the radio programs on magnetic tape was a common professional practice, the only documents that could be considered today are the written texts of the radio programs (conferences, educational or informative programs, political, agricultural news, etc.).

Between 1925, when The Romanian Society of Radiotelephony was established, and 1948, the year when the communist regime officially came into power, Romanian radio programs broadcast discourses on a broad range of topics and for a large audience. The present study focuses on the ethnological one. We are interested in how the ethnological discourse rooted in the aforementioned time period also built a media hypostasis for addressing the entire society, and in how programs dedicated to “traditions” bear the signs of this structuring process.
Social Change, Dress and Identity
Authors: Fülemile Ágnes
Published: March 2021

The article, based on extensive ethnographic fieldwork, studies the process of the disintegration of the traditional system of peasant costume in the 20th century in Hungary in the backdrop of its socio-historic context. There is a focused attention on the period during socialism from the late 1940s to the end of the Kádár era, also called Gulyás communism. In the examined period, the wearing and abandonment of folk costume in local peasant communities was primarily characteristic of women and an important part of women’s competence and decision-making. There was an age group that experienced the dichotomy of peasant heritage and the realities of socialist modernisation as a challenge in their own lifetime – which they considered a great watershed. The author interviewed both the last stewards of tradition who continued wearing costume for the rest of their lives and those who pioneered and implemented changes and abandoned peasant costume in favor of urban dress. The liminal period of change, the character and logic of the processes and motivations behind decision-making were still accessible in memory, and current dressing practices and the folklorism phenomena of the “afterlife” of costume could still be studied in real life. The study shows that costume was the focus point of women’s aspirations, attention, and life organization, and how the life paths of strong female personalities were articulated around clothing. It also reveals that there was a high level of self-awareness and strong emotional attachment in individual relationships to clothing in the rural context, similar to – or perhaps even exceeding – the fashion-conscious, individualized urban context. Examining the role of fashion, modernization, and individual decisions and attitudes in traditional clothing systems is an approach that bridges the mostly distinct study of folk costume and the problematics of dress and fashion history research.
Cottage Industry Co-Operatives with Applied Folk Art Profile in Hungary after World War II
Authors: Ament-Kovács Bence
Published: March 2021

This study deals with the history of the Hungarian cottage industry co-operatives with applied folk art profile after World War II. Since publications in this topic concerning Hungary are scarce, this framework is dedicated to the circumstances under which these co-operatives which employed a high number of people and operated quite successfully up to the beginning of the eighties, came into existence, their operations and the scope of objects produced by them, which are identified as applied folk art today. Having the economic, political and cultural environment of the Rákosi- (1949–1956) and Kádár-era (1956–1989) in mind, just as well, as the current approach of creators and ethnographers to the activity of the co-operatives.
The Voice of the Lord from a Record Player (Vietnamese Highlands, 1960s)
Authors: Vargyas Gábor
Published: March 2021

In this paper, I present a short excerpt from an 18-hour-long Bru life history recorded in 1989 in the Central Vietnamese Highlands among the Bru/Vân Kiều of Quảng Trị. The excerpt sheds light on the circumstances of Christian evangelization among the Bru through the recollections of a Bru man who was not Christian himself but was in contact with the key protagonists of the events, the missionaries and the evangelized Bru people. The interview reveals on how the evangelized and non-evangelized viewed the evangelists. What were the ways of promoting evangelization? Were the Bru impressed by the world of the evangelizers? How did the Bru conceive of the evangelizers? How convincing did they find their arguments? Beside its immanent value, this intercultural encounter has a significance beyond itself insofar as it is situated in and reflective of the icy political and ideological milieu of the Vietnam War in the 1960s–1970s, the impacts of which were still lingering when the recording was made.

Published: March 2021

This paper introduces research on magnetic fields with special attention to developing a new method for braking fast-changing alternating movements. This work is part of a research project aiming to find the most efficient and accurate method for development of linear magnetic brake for dynamic tests in industrial applications. In applications requiring precisely defined and generated characteristics of the braking force, highly reliable and accurate function between the braking force and the controlling current should be investigated.

The goal of this research is to develop accurate and reliable control methods for fast changing magnetic fields used in automatic test solutions of different devices and tools, which have been tested manually before.
Mobilizing the Social Power of Iconic and Performative Texts for Justice and Reform
Authors: Watts James W.
Published: March 2021

In the ten years of its existence, SCRIPT has succeeded in promoting and publishing an increasing variety of scholarship on iconic and performative texts. Culturally specific studies have provided the basis for comparative theorizing about the phenomena. This body of scholarship has put us in a better position to analyze current events involving iconic books and performative texts. It can also enable us to make creative suggestions for strengthening movements for justice and social reform by ritualizing iconic and performative texts. Here, I provide three examples of how to employ SCRIPT research to strengthen contemporary movements for social and environmental justice: a short-term episodic intervention, a medium-term structural rectification, and a long-term cultural innovation.
