The edge-to-edge geodetic domination number of a graph
Authors: John J. , Sujin Flower V.
Published: April 2021

Let G = (V, E) be a connected graph with at least three vertices. A set S ⊆ E(G) is called an edge-to-edge geodetic dominating set of G if S is both an edge-to-edge geodetic set of G and an edge dominating set of G. The edge-to-edge geodetic domination number γgee(G) of G is the minimum cardinality of its edge-to-edge geodetic dominating sets. Some general properties satisfied by this concept are studied. Connected graphs of size m with edge-to-edge geodetic domination number 2 or m or m − 1 are characterized. We proved that if G is a connected graph of size m ≥ 4 and Ḡ is also connected, then 4 ≤ γgee(G) + γgee(Ḡ) ≤ 2m − 2. Moreover we characterized graphs for which the lower and the upper bounds are sharp. It is shown that, for every pair of positive integers a, b with 2 ≤ a ≤ b, there exists a connected graph G with gee(G) = a and γgee(G) = b. Also it is shown that, for every pair of positive integers a and b with 2 < a ≤ b, there exists a connected graph G with γe(G) = a and γgee(G) = b, where γe(G) is the edge domination number of G and gee(G) is the edge-to-edge geodetic number of G.

Cooperation between Russia and Germany in the field of energy policy in the XX-XXI centuries
Authors: Babintseva Ekaterina Alekseevna , Ponomarenko Lyudmila Vasilievna
Published: April 2021

The author devoted the paper to the peculiarities of bilateral cooperation between Russia and Germany in the field of maintaining a favourable environmental balance. The author notes that nature protection for a long time was not considered as a subject of interstate cooperation and did not fall into the focus of the agenda of important international summits. In connection with a number of historical reasons, at the beginning of the last century there was minimal state interest in organizing the protection of protected areas, conducting stabilization and supporting environmental measures, as well as ensuring the conservation and renewability of natural resources. The extensive path of economic development, the devastating military operations and the assessment of the natural environment as a resource basis for achieving primary state tasks contributed to the development of the global environmental crisis by the middle of the 20th century. The paper emphasizes that the starting point of international environmental cooperation and the adoption of a number of universal environmental acts were reports within the framework of the Club of Rome and further multilateral summits on climate and environmental issues dating back to the second half of the 20th century. The author assigns a special role within the framework of Russian-German environmental cooperation to the Nord Stream and Nord Stream-2 gas pipelines. The author emphasizes that cooperation within the framework of the projects took place in the context of the Western sanctions on Russia. Using energy projects as an example, the author showed in action the environmental relationship in the process of fuel and energy dialogue between partner countries. Based on an analysis of the results achieved, the author concludes that the future environmental cooperation between Russia and Germany is promising.

PERANAN DAN SUMBANGAN NIK RAHIMAH NIK IDRIS DALAM BIDANG SULAMAN KELINGKAN
Authors: Ab. Rahman Norhayati Ab. Rahman , Abdul Majid Maizira
Published: April 2021

The ‘kelingkan’ embroidery is a traditional Malay art passed on from generation to generation. The art received the highest recognition from female nobility and aristocrats who wore it to important events in olden times. However, the art of embroidering ‘kelingkan’ faces extinction due to a decrease in demand from the community because of its high cost and shortage of skilled ‘kelingkan’ embroiderers. Moreover, there is a lack of reference materials and documentation of ‘kelingkan’; hence it is not widely known today. This paper, therefore, aimed to introduce a prominent ‘kelingkan’ practitioner from Kelantan named Nik Rahimah Nik Idris. The research delved into her role and contribution towards ‘kelingkan’ embroidery, specifically in Kelantan and Malaysia in general. Researchers conducted a literature review and then fieldwork to interview ‘kelingkan’ embroiderers. The results were then evaluated through content analysis. Findings showed that Nik Rahimah is indeed an important figure in the art of ‘kelingkan’ as she was a royal embroiderer, ‘kelingkan’ demonstrator, expert and promoter of the art in Malaysia and abroad. As such, she has made a significant contribution in upholding and preserving the art of ‘kelingkan’ embroidery. Keywords: role, embroiderer, kelingkan, Kelantan.
HUBUNGAN ALAM DAN MANUSIA DALAM FILEM TOMBIRUO: PENUNGGU RIMBA (2017)
Authors: Abdullah Nur Afifah Vanitha , Muhd Shukri Fatimah , Mohd Rosdi Nur Aifaa Nabilah
Published: April 2021

‘Tombirou: Penunggu Rimba’ (2017) (TPR) is a mystical action film based on the rural Sabahan community belief about nature. More than 99 per cent of this film was shot in forested areas, therefore relevant to the film’s ultimate idea, which is the importance of caring for nature and striking that balance between nature and man. The film also contains symbolism that conveys nature’s revenge against man for their irresponsibility. Thus, this paper studied the portrayal of man and nature in TPR. An approach was devised with content analysis as a tool to answer the said question. This was supported by applying Aldo Leopold’s ecocentrism (1949) to analyse the film. The primary research material was TPR, whilst additional data was retrieved from books, journal articles and newspaper articles. Findings showed that this film had portrayed the importance of preserving the balance between nature and man in life’s ecosystem. This factor is vital to ensure nature’s wellness and the balance between man and nature. The characters Tombiruo, Tobugi, Bobolian and Pondolou were also shown as agents of peace, mediators and caretakers of nature. Keywords: ecocentrism, Tombiruo: Penunggu Rimba, Malay film, film criticism, symbolism.

The art of traditional Malay massage is one element of local wisdom that should be given more attention. Various external influences increasingly taint such massages in Malaysia and to some extent changed the art itself. This study, therefore, aimed to identify the local community’s acceptance of traditional Malay massage and their openness in embracing local arts. The study also sought the public view on the future of traditional Malay massage. The paper, supported by the concept of human nature by Rousseau (1967), also collected responses from 200 respondents of various backgrounds through the distribution of online questionnaires. The study found that the traditional arts still have a place amongst the Malay community. Besides, it was proven that elements of external influences had been observed in traditional Malay massage. The implications of the study indicate that a concerted effort needs to be made to preserve this heritage art in order for it to remain relevant and produce more practitioners. Keywords: local wisdom, arts of traditional Malay massage, massage, concept of human nature.
Non-surgical treatment of a coronarography-induced iatrogenic aortic dissection
Authors: d'ostrevy nicolas , cassagnes lucie , Durel nicolas , Camilleri Lionel
Published: April 2021

Coronary dissection is an extremely rare but known complication of
coronary catheterization and angioplasty. Due to its rarity, there are
no management recommendations. However, surgery immediately after an
endovascular procedure is frequently carried out under major
antithrombotic treatment. The surgery and the postoperative consequences
are therefore very complex. We report here the documented case of a type
A aortic dissection after coronary catheterization. Despite extension to
the entire ascending aorta which indicated surgical management, the
benefit-risk balance argued for armed surveillance to avoid surgery
under antiplatelets drugs without known antidote. We believe this case
should lead us to systematically weigh the data before considering that
any iatrogenic dissection of Dunning class 3 should be operated.

Published: April 2021

Background Dietary inflammatory index (DIP) is a new dietary index
designed to evaluate individuals’ diets. In addition, adhesion molecules
are important biomarkers for assessing endothelium inflammation that
they related to atherosclerosis and cardiovascular disease. Also, there
is no study for assessing the association between adhesion molecules and
DIP until now as well as other studies that assessed the relationship
between dietary inflammatory index or DIP have controversy. Aim of the
Work The purpose of this cross-sectional study was to determine the
correlation between DII and endothelial markers such as E-selectin,
intercellular adhesion molecule-1 (sICAM-1) and vascular cell adhesion
molecule-1 (sVCAM-1) among female nurses from Isfahan. In this study,
dietary inflammatory potential (DIP) was used instead of DII. Patients
and Methods This study was performed on 420 healthy nurses. The nurses
were selected by random cluster sampling method from private and public
Isfahan hospitals. A validated food frequency questionnaire (FFQ) was
applied to assess the dietary inflammatory potential. A fasting blood
sample was collected for measuring the plasma levels of the endothelial
markers and other variables. Results After adjusting different potential
confounders, no statistical association was found between DIP and
sICAM-1, E–selectin and sVCAM-1 in model I (P=0.57, 0.98 and 0.45),
model II (P=0.57, 0.98 and 0.45) and model III (P=0.67, 0.92 and 0.50)
in comparison to the crude group (P=0.35, 0.83 and 0.49, respectively).
Conclusion The results revealed that the plasma levels of endothelial
markers including E-selectin, sICAM-1, and sVCAM-1 were not
significantly associated with DIP in female nurses.

Authors: Ozkent Mehmet Serkan , Yılmaz Burak , Hamarat Mustafa , Eroglu Esma
Published: April 2021

Purpose: The novel coronavirus disease 2019 (COVID-19) has spread all
over the world. The diagnosis of COVID-19 in asymptomatic patients and
patients with non-respiratory symptoms remains a big concern. In this
study, we aimed to evaluate the incidence of missed diagnosed COVID-19
pneumonia on abdominal computed tomography (CT) performed in patients
admitted to our urology outpatient clinic. Methods: We reviewed the
files of patients who were admitted to the urology outpatient clinic
from 1 April to 1 November retrospectively. We included the patients who
performed abdominal CT at the urology outpatient clinic for any reason
and recorded demographic data and abdominal CT findings. We excluded
patients with pulmonary symptoms and previously diagnosed with COVID-19.
Also, patients without abdominal CT were excluded. We evaluated the
rates of missed diagnosed COVID-19 pneumonia detection on the lung base
images of abdominal CT. Results: 1024 patients were included in this
study. We observed that 99 (9.7%) of these patients had findings
related to COVID-19 pneumonia on the lung base images of abdominal CT.
Although 885 (86.4%) patients had no pathological pulmonary findings,
40 (3.9%) patients had other pathological pulmonary findings.
Conclusion: COVID-19 disease has become a pandemic all over the world.
All healthcare professionals, including urologists, play an active role
in the diagnosis and treatment of this disease. So, it should be kept in
mind that COVID-19 pneumonia should be evaluated in patients admitted to
the urology outpatient clinic with renal colic or abdominal pain.

Authors: Bilac Mariana Carvalho , Passos Luiz Santana , Gama Romana Santos , Souza Renato Morais , Amorim Welma Wildes , Macedo Jessica Caline , Queiroga Hevila Maciel , Oliveira Marcio Galvão
Published: April 2021

Aims: Adherence to prescribed treatment is important for obtaining the
desired outcomes in older people care. Polypharmacy is strictly
associated with adherence, and complex pharmacotherapy can lead to poor
adherence and unexpected outcomes, which are aggravated by older age.
The medication regimen complexity index has been proven to be a valid
and reliable tool for quantifying the complexity of medication regimens.
The objective of the present study was to evaluate the therapeutic
complexity of drugs used by older people in a primary care setting in
Brazil. Methods: This was a cross-sectional study conducted in 22 basic
health units in Brazil. Older people from this sample who were treated
in a primary care setting were interviewed after a consultation with a
family practice physician. Data were collected from September 2016 to
March 2019. Patients aged ≥ 60 years who visited the primary care units
were included in the study. Pharmacotherapeutic complexity was assessed
according to the medication regimen complexity index. Results: In all,
675 individuals with a mean age of 70 years (±7.1 years) were included.
The mean number of drugs prescribed per capita was 2.9 (±1.8). The
median medication regimen complexity index for the sample was 8.0, and
26.1% of the patients interviewed had a high medication regimen
complexity index. Conclusion: The complexity of the drug regimen was
high in almost one-third of the prescriptions analysed. This high
complexity might contribute to non-adherence to medication regimens,
leading to safety- and effectiveness-related issues. Key words: drug
prescriptions, geriatrics, pharmaceutical preparations, polypharmacy,

Concept of polycentricity-the differences between development policies and spatial reality
Authors: Zivanovic Vedran , Pavlovic Mila , Kovjanic Aleksandar , Tosic Dragutin , Krstic Filip
Published: April 2021

Contemporary scientific literature and strategic documents suggest the
concept of polycentricity as a key factor and the aim of regional
development policies. One of the aims of this study is to analyze spatial
relations between the nodal regions and to determine (calculate) the level
of polycentricity in the region of Vojvodina (Northern Serbia). By
quantifying spatial relations in the region (using selected methods), we
pointed out the relevance of regional development policies, i.e., the extent
to which the proposed measures for reducing regional inequalities are in
line with the direction of contemporary spatial relations in the region of
Vojvodina. We have used four different methodological tools: rank-size rule,
urban primacy index, index of functional centrality, and commuting patterns
(levels of functional dependence). The obtained results identified the
existence of morphological polycentricity, but also the growing domination
of the cities of Novi Sad and Belgrade in regulating and managing spatial
and functional relations in the region of Vojvodina. These results are not
completely in line with the development directions declared in the strategic
documents. Our approach focuses on assessing the influence of the main nodal
(sub)centers in managing further spatial and functional relations in the
region of Vojvodina.

Published: April 2021

Research on tourism routes is mainly focused on their development from the
perspective of stakeholders, co-operation, and networking, but there are
very few which explore them from the perspective of its users. In order to
expand the tourist offer of Novi Sad (northern Serbia), one thematic route
that promotes a part of the literary heritage was created. The aim of this
study was to analyze the given literary route from a tourist perspective,
checking out whether this route was created in a way that would satisfy its
users. For this purpose, an experiment was conducted in which 50 students of
tourism were divided into two simulated tours with a specialized tour guide.
They were asked to use the ArcGIS application installed on their mobile
phones to fill up a questionnaire about the literary route while moving
through the selected checkpoints in the city center. The results provided
answers to the questions like: whether the attractions of the given
localities that the route links are properly selected, whether the thematic
tour is good regarding the attraction order and whether it is in line with
the growth of emotions of joy and positive surprise, which segments on the
route should be improved in order to increase its quality, whether the route
contributes to the tourist satisfaction that will create a desire for a
route recommendation, and whether the route is appropriate to be offered to
tourists, as well as to the locals. According to the preliminary results,
the authors gave recommendations for the route improvement before its
implementation on the tourist market.

Published: April 2021

This paper deals with the tribological behavior of thermal barrier coating in engine liner and it also deals with the quality of thermally treated coating. Multi-layer structure formed from top coat and bond coat which was deposited on the same type of steel substrates, in which heat treatments may improve the mechanical properties of materials both substrate and coating and enhance their hard-ness for many cases of ceramics through recrystallization of microstructures. In addition, heat treatments will introduce residual stresses by different thermal contractions and lattice misfits because of microstructural changes that could lead to either premature failure or stress relaxation by new crack formations. Tribological wear properties of differently treated thermal barrier coating was examined to see the net effect of heat treatment on mechanical properties by tribometer with pin on disc mode. Indentation test at surface and cross-section of coatings are examined. The SEM and optical microscope examine several crack propagations. Energy-dispersive X-ray spectroscopyhelps to characterize thermal barrier coating. After thermally treating the sample, an examination of thermal barrier coating the oxide content was increased, sample became convex due to residual compressive stress, roughness reduces, adhesion between topcoat, and bond coat get reduced eventually. In addition to that, the surface gets cracks due to the reduction in hardness from 330 HV to 212 HV.

La inducción al trabajo interdisciplinario a partir de la imagen en el arte y la literatura como herramienta para propiciar la problematización de la transdisciplinariedad
Authors: Martínez Puente Lourdes Yunuen
Published: April 2021

En este artículo se reflexiona en torno al trabajo interdisciplinario de las artes y la literatura como propuesta ante las problemáticas que presenta la educación superior en la actualidad y para hacer visible la importancia de la transdisciplina en este contexto. Esta reflexión también está encaminada a aportar elementos teóricos y prácticos como material académico de la materia Fundamentos teóricos de artes visuales, que forma parte del curso propedéutico de la maestría en Estudios Interdisciplinarios en Arte y Humanidades de la Universidad Autónoma de Querétaro. El análisis se realiza a partir de cinco apartados: el concepto de figura[1] a partir de la propuesta de Raúl Dorra, un enfoque por competencias cooperativas, el concepto de racionalidad, el método hermenéutico crítico y la concepción de interrelaciones dialogales y de interacciones disciplinares. Por último, se muestran los resultados en torno a la problemática planteada a partir de su caracterización y posible pertinencia.

 

[1] En su libro La retórica como arte de la mirada (2002), Raúl Dorra concibe el discurso literario o poético como “un cuerpo que hace figura”. El cuerpo/figura deviene espectáculo para la mirada. La propuesta de Dorra será el medio de aproximación para reflexionar sobre ese cuerpo que hace figura en obras plásticas, literarias, en incluso, investigativas. Para el escritor argentino, la construcción de la idea occidental de discurso, desde su designación como “figura del discurso”, establece una relación de analogía con el cuerpo. Mas no se trata de cualquier cuerpo, sino un cuerpo humano modelado por una disciplina como la gimnasia o la danza. Es en este sentido que las palabras nos remiten a la tensión de un cuerpo que se ofrece como espectáculo y de esta manera “hace figura”: “La figura sería originalmente, entonces, la que hace el gimnasta o el bailarín cuando, frente a un público también educado por el arte, tensa su cuerpo y lo ofrece a la mirada convertido en espectáculo. Así, el cuerpo hace figura en el momento en que trasciende su densidad somática y adquiere la propiedad de ser pura forma” (Dorra, 2002, p. 18).
Психологические особенности личности младших школьников с разным уровнем академической успеваемости
Authors: Зинина Валерия А.
Published: April 2021

Статья посвящена изучению актуальной психолого-педагогической проблемы, а именно проблемы школьной успеваемости. Научная новизна исследования состоит в анализе мотивации к обучению и тревожности в качестве факторов, оказывающих воздействие на уровень академической успеваемости младших школьников. В разделе Введение обозначены актуальность исследования, его цель и гипотеза. Теоретический анализ литературных источников показал, что личностные качества влияют на успеваемость школьников. В разделе Методы обозначены объект и методы исследования. Объектом исследования выступили младшие школьники (4 класс) Лицея № 27. Участие принимали как девочки, так и мальчики в количестве 72 человек. Исследование было проведено осенью 2020 года. Методы исследования: тестирование «Направленность на приобретение знаний» (Е. П. Ильины, Н. А. Курдюкова) и Шкала явной тревожности CMAS (А. М. Прихожан). Раздел Результаты включает в себя полученные авторами данные. В эмпирической части исследования были получены следующие результаты: школьная мотивация связана с академической успеваемостью, то есть чем выше учебная мотивация, тем выше уровень успеваемости у школьника; уровень тревожности не связан с академической успеваемостью; была выявлена обратная взаимосвязь между уровнем мотивации к обучению и тревожностью, то есть чем выше тревожность, тем ниже мотивация к обучению. Гипотеза подтверждена частично. В разделе Обсуждение результатов автор говорит о ряде направлений для дальнейших исследований. Была намечена разработка рекомендаций для педагогов.

Teachers experience particular difficulties in learners’ writing activities for academic purposes. Teachers should concern more about this phenomenon. One of the strategies to explore this fact is by determining an assessment procedure to encompass the writing direction during the learners’ writing process. Understanding learners’ difficulties and defining direction to solve those difficulties are significant for teachers to develop writing direction. This research applied a case study method to investigate the directional concern that Indonesian high school teachers’ arranged derived from a think-aloud protocol (TAP) assessment, which the researcher suggested. The researcher interviewed three Senior High School teachers about the argumentative writing performance of their three learners by applying the TAP Assessment. After the TAP assessment, the teachers’ directional concerns contained more elements related to the process of writing, even though they still ignored several significant processes. The inference result was that writing teachers’ professional development gave directional plans so that teachers were facilitated to work on writing assessment data thoroughly for the whole organization aspects.

This study aimed to determine the effect of scarification using goat urine with different soaking time on the quality of gamal seeds (Gliricidia sepium) and determine the best scarification treatment that produces normal sprouts and the best sprouts. This research was conducted in January 2020, located in the Laboratory of Animal Nutrition and Feed, Department of Animal Husbandry, Faculty of Agriculture, University of Lampung. This study used an experimental method using Completely Randomized Design with 5 treatments (control or without soaking, seed soaking for 4, 8, 12, and 16 hours) and 6 replications. Each trial unit received 30 seeds of Gamal. Data analysis was performed using the ANOVA continued by the least significant difference (LSD) test. The results showed that scarification of gamal seeds in goat urine at different times of soaking gave significantly effect (P <0.05) on germination, normal sprouts, dead seeds and hard seeds, but did not affect on abnormal sprouts and yield attacked by pests. The best scarification treatment for normal sprouts and sprouts rate was soaking for 16 hours, namely 60.00% and 47.73%, respectively. This results showed the longer soaking the seeds, the higher the germination and normal sprouts.
