Authors: Nor NFM , Sinniah SD , Dasor MM
Published: March 2022

Objectives: To assess oral health related quality of life (OHRQoL) among orthodontic patients who had been allocated into three methods of orthodontic anchorage; transpalatal arch (TPA), modified TPA-Nance (TPA-Nance) and mini-implant (MI). Materials and Methods: This study was conducted in Faculty of Dentistry, Universiti Teknologi MARA, Sungai Buloh and Puncak Perdana campus. Thirty-six orthodontic patients with anchorage requirement between 18 and 30 years old were recruited. The subjects were equally divided into three groups, which included 28 females and 8 males. The assessment of patients’ oral health related quality of life (OHRQoL) towards the anchorage supplementation using modified oral health impact profile (S-OHIP-14) questionnaires were carried out. The questionnaire was given at two time points, which was before the insertion of the allocated anchorage regime (T0) and after a week of insertion of the allocated anchorage regime (T1). Results: There was no statistical significant difference on functional limitation, physical pain, psychological discomfort, physical disability, psychological disability, social disability and handicap domains of OHIP-14 questionnaire between the three anchorage groups (p>0.05). Conclusion: The OHRQoL patterns, during the treatment with the anchorage reinforcement were very similar. This suggests that TPA, TPA-Nance and MI do not affect patients’ OHRQoL. The OHRQoL trends observed during the study can be communicated to patients and used to increase patients’ compliance since they are made aware of the whole treatment process.
Removal of Failed Dental Implant with Application of Concentrated Growth Factor (CGF): A Case Report
Authors: Yusof NAM , Masri MS , Noor E
Published: March 2022

Introduction: High survival rates of dental implants were commonly reported even after 10 years of follow up. Nevertheless, complications and failure may occur and the implant would need to be removed. In recent years, the use of autogenous blood products in dental surgery has increased due to its ability to aid the healing of the soft and hard tissues. Clinical case: The case demonstrated the utilisation of concentrated growth factor (CGF) from the patient’s blood for healing following conservative removal of a failed dental implant. Subsequently, the patient showed satisfactory recovery without any infections and clinical complaints. Conclusion: This explantation procedure, together with the use of CGF, may prevent the normal bone resorption and accelerate soft tissue healing. As it is biological in nature having originated from the patient’s blood, it is more readily accepted by the tissues and the risk of infection is low.

Published: March 2022

Objective: To evaluate the root debridement skill in periodontology pre-clinical module among dental students and to estimate the effectiveness of conducting periodontology pre-clinical module before entering clinical module. Materials and Method: A total of 47 pre-clinical dental students (Year 2) were included in this study. Single rooted extracted teeth were collected, mounted on acrylic resin and set into the level of 1/3 of the root length. Each of them were instructed to prepare a mounted teeth and to perform root debridement procedure on the labial surface of the tooth only within 10 minutes using Gracey curette #5/6. The similar samples were distributed back to the same students (which were already in clinical year (year 4) to repeat the same procedure on the lingual surface of the same tooth. Root surface roughness was evaluated by using scanning electron microscope (SEM) and profilometer for both labial and lingual surfaces. Statistical analysis was done using Mann-Whitney U test and T-test. Significance level of p ≤ 0.05 was assumed for all analysis. Results: SEM photomicrographs of root surfaces with magnifications of 100x and 800x revealed that there were incomplete removal of the dental calculus in both surfaces and significant roughness root surfaces noted. Conclusion: No significant differences noted between the students’ root debridement skill in the pre-clinical and also clinical year. Objectives of the current module were fulfilled but in order to meet the highest standard, current module need to be improved in the future.

Published: March 2022

Objectives: This study aimed to assess intra- and inter-examiner reliability of International Caries Detection and Assessment System (ICDAS) and modified epidemiology ICDAS (MOD) code by undergraduate dental students with different clinical experiences. Methods: A total of 150 dental undergraduate students with varying clinical experiences (0, 1 and 2 years of clinical experience) were recruited. Participants received training through a theoretical lecture on ICDAS criteria by an experienced National Benchmark Group (NBG) examiner and underwent e-learning program prior to ICDAS calibration. Visual examination on extracted permanent teeth (N= 45) with different location and stages of caries progression ranging from ICDAS scores 0 to 6, was performed using the ICDAS criteria. The assessments were repeated after one hour. The data were analysed to evaluate inter-examiner and intra-examiner reliability in the form of kappa scores using SPSS 23 Software. Results: Mean kappa values for intra- and inter-examiner reliability for ICDAS code, were between 0.41 to 0.60, and 0.61 to 0.80 respectively. For MOD code, mean kappa values for intra- and inter-examiner reliability were between 0.61 to 0.80. Good intra-examiner agreement (>0.61) was observed in both ICDAS and MOD code for all groups. Conclusion: All students performed similar agreement, therefore, clinical experience within 2 years does not influence the performance of visual inspection in detecting caries using ICDAS. The results of the study shows that ICDAS and modified epidemiology ICDAS codes has good reproducibility and is feasible to be used as a tool in clinical practice as well as patient education.

Published: March 2022

Physical sporting activities is beneficial for your health. It has to be continuously and constantly performed route in creating positive and healthy lifestyle as it involves self-discipline.  It needs a special interest and a positive mindset to attract students to take up sporting activities. The objective of this study is to assess the students’ interest in sports based on several factors among the excellent students. The samples for this study are a group of students (N = 420) comprises of male (n = 210) and female (n = 210) with the age of 16 years old, selected based on simple random sampling. Questionnaire forms were used as a method for data collection. Descriptive and inferential analysis was used to look at the factors influencing students’ sporting attitudes based on demographic data. The result shows that there are four factors highly influencing sporting attitudes. However, only the aspect of value that has significance different from gender p <0.05, where male students are higher than female. Nevertheless, the most significant factor is gender, p<0.05, where male students found to be higher than female. This value aspect is a preliminary consideration of the advantages or disadvantages of sports. Sporting assessment also depends on the effectiveness of teaching by educators who shape the behavior of students to pick up sports. Hsiao (2009) emphasizes the attitude of teachers or lecturers who care about students, know what is being taught, easy to discuss and make teachers and lecturers happy to be with them.

Investigaciones académicas / Investigaciones artísticas
Authors: Bravi Carolina Anabel
Published: March 2022

En las últimas décadas, artistas e investigadores han comenzado a reflexionar sobre la relación entre los procesos de creación y las formas de validación de los saberes científicos. Para ello se plantea que la obra artística puede ser una instancia de producción de conocimiento que utiliza procedimientos artísticos para visibilizar realidades que, para la ciencia tradicional, no resultan tan evidentes. Este trabajo plantea que las investigaciones basadas en la práctica artística constituyen un punto de encuentro entre el campo del arte y el de la ciencia; luego revisa sus aportes teóricos y metodológicos, y finalmente reflexiona sobre las posibilidades y formas de trasferencia a la formación grado en las carreras universitarias vinculadas con la producción artística.
Revisitando las Giocondas del Louvre, el Prado e Isleworth
Authors: Boyano José T. , Boyano Delia
Published: March 2022

Actualmente existen tres versiones de la Gioconda de alta calidad, una en el Louvre, otra en el Prado y la tercera en la colección Isleworth. Tras la restauración de 2010 realizada en el Museo del Prado, se ha discutido mucho su autoría. En este trabajo, analizamos el estilo de los principales candidatos propuestos por la historiografía, centrándonos en Fernando Yáñez de la Almedina y Salai. Revisamos el modo de colaboración en el taller de Leonardo, apoyándonos en La Virgen del huso. Nuestras conclusiones apuntan a Fernando Yáñez como autor de la Mona Lisa de Isleworth, por su concordancia con obras conocidas de este pintor; y realizada en colaboración con Leonardo, por la calidad de su diseño, manos y rostro. La Gioconda del Prado sería obra de Salai, si bien su alta calidad nos sugiere una participación importante de Leonardo en su diseño y ejecución. Un análisis informatizado de los colores presentes en las dos versiones de la Gioconda y su comparación con obras de Yáñez y Salai podría confirmar estas hipótesis en el futuro.
Más allá de los objetos
Authors: Carlón Clara , Lucentini Verónica
Published: March 2022

Este trabajo propone analizar la instalación Patrimonio (2003) de la artista argentina Ana Gallardo a la luz de lo que consideramos como giro performativo de las artes visuales. Bajo esta perspectiva, la obra emerge como evidencia de un repertorio de acciones previas que, mediante una serie de estrategias poético-simbólicas, promueve relaciones de proximidad y distanciamiento con la vida cotidiana. En este sentido, esta instalación se devela como un territorio poroso entre disciplinas y materialidades múltiples que se desplazan entre lo escénico y lo visual, transformando las experiencias vivenciales y corporales en material artístico.
Tres apuntes sobre memoria, filiación y arte
Authors: Jofre Jorge
Published: March 2022

Los tres apuntes, referidos a aspectos de la memoria y la filiación en situaciones posicionadas en el campo del arte, son el soporte fundamental del presente artículo. La redacción de ellos intenta, sobre todo, presentar cuestiones sobre el tema que luego podrían ser tratadas en versiones ampliadas. De allí que los registros viabilizadores de la propuesta sean solo una crítica de Lucas Fragasso sobre una retrospectiva del Di Tella; un documental de Federico Actis sobre un centro clandestino que funcionó en Rosario; y una ponencia de Justo Pastor Mellado que busca aclarar ciertas periodizaciones del arte en Chile. Tras el análisis, ciertos hallazgos: la memoria como un ejercicio y también a modo de un registro de sucesos; la filiación y la construcción de identidad en un cruce nodal con el arte. Por último, una breve consideración sobre memoria y olvido.

Influence of fertilisation and crop rotation on grain yield and quality of winter wheat (Triticum aestivum L.)
Authors: Babulicová Mária , Gavurníková Soňa
Published: March 2022

At the present time, crop rotations are constantly adapted to economic conditions and one or two main crops are grown in agricultural farms. This has a negative impact on the environment. The optimization of grain yield and quality of winter wheat are dependent not only on the appropriate crop rotation but also on the nitrogen fertilisation. The aim of this study was to examine the effect of crop rotations, fertilisation and preceding crop on grain yield and quality of winter wheat during the years 2015/2016 – 2017/2018. The grain yield of winter wheat after preceding crop pea in crop rotation with 40% proportion of cereals was statistically higher (5.91 t/ha) than in crop rotation with 80% share of cereals (5.55 t/ha). In the treatment with mineral fertilisation and organic manure Veget® incorporation, the grain yield was statistically higher (6.00 t/ha) than in the treatment with mineral fertilisation (5.50 t/ha). According the standard STN 46 1100-2:2018 based on the wet gluten content, the winter wheat grain was classified into the class E by mineral fertilisation + organic manure Veget® in all monitored years. In 2017 the winter wheat grain was categorized into the class P based on wet gluten content in crop rotations with 80% proportion of cereals in the treatment with fertilisers only after preceding crop winter barley.

Authors: Dhawan Kanika , Vats Ramesh Kumar , Agarwal Ravi P.
Published: March 2022

In this manuscript, we have studied the coupled system of Hilfer fractional differential equations with non-local conditions. We have used the Leray-alternative Schauder’s and the Contraction principle to obtain the results on the existence and uniqueness of the solution of the proposed problem in the weighted space of continuous functions. For the defined problem, sufficient conditions have also been developed to determine the Ulam stability of the solution. The key conclusions are well-illustrated with examples.
Case Studies on Finite Element Modeling of Welded Joints
Authors: Heinemann Patrick , Isopescu Dorina , Maxineasa Sebastian George
Published: March 2022

Joints made out of tubular steel members are often used in industrial constructions, like offshore, trusses or tree-shaped columns. The joint area is the weakest point in a truss structure. Beside the normal static behaviour many non-linearities due to the geometry or to the welding process have to take into account. Steel hollow sections are often used. Much research was made on welded nodes so far, but mostly it is valid for limited geometries or load cases. A review of the main aspects in designing welded nodes are given.

The second part is about a study of two aspects. The first aim is to investigate the influence of the joint angle on the resistance of a T-joint made out of Circular-Hollow-Sections or Squared-Hollow-Sections under a tensional load. To archive the most realistic results, the second aspect, a numerical study on the finite element types and the element shape functions will be made.
Moth flies (Diptera: Psychodidae) of the Moravskoslezské Beskydy Mts. and Podbeskydská pahorkatina Uplands, Czech Republic, III.
Authors: Kroča Jiří , Ježek Jan
Published: March 2022

Here, we present the latest findings on moth fly (Psychodidae: Diptera) species richness in the Moravskoslezské Beskydy Mts. and Podbeskydská Pahorkatina Uplands, based on both previously published and unpublished data and new samples collected between 2007 and 2020. Two species new to the fauna of the Czech Republic were recorded (Sycorax feuerborni Jung, 1954 and Jungiella (Jungiella) revelica Vaillant, 1972), bringing the total number of moth fly species in the Czech Republic to 180 (Ježek et al. 2021). In addition, five species were recorded for the first time in the area of interest: Trichomyia parvula Szabó, 1960 (second locality in the Czech Republic); Paramormia (Phyllotelmatoscopus) acuta (Krek, 1971) (third record in the Czech Republic); Philosepedon (Philosepedon) perdecorum Omelková & Ježek, 2012 (third locality and fourth record); Pericoma (Pericoma) ljubiniensis Krek, 1969 (second finding and third locality); Tonnoiriella pulchra (Eaton, 1893) (sixth area and first finding in the Czech Carpathians). The finding of Jungiella (Jungiella) valachica (Vaillant, 1963) confirms its historical occurrence in the region. In the latest survey, we collected 108 species from 29 localities, of which 16 are critically endangered, eight endangered and three vulnerable. Nine localities were evaluated as species-rich, i.e. Hluchý 1. (58 species), Vysutý 2. (56), Hluchý 2. (53), Vysutý 4. (49), Skalická Morávka 2. (46), Chladná voda 3. (44), Hluchý 3. (43), Morávka - spring and Obidová 1. (both 42). The total number of moth flies found within the Moravskoslezské Beskydy Mts. and Podbeskydská pahorkatina Uplands now stands at 124 species, representing 68.9 % of total Czech fauna.
Stoneflies (Plecoptera) of the Moravskoslezské Beskydy Mts. and the Podbeskydská pahorkatina Uplands, Czech Republic. I. Systellognatha
Authors: Kroča Jiří
Published: March 2022

Publications up to 2011 record 21 species of stonefly, infraorder Systellognatha, as occurring in the Moravskoslezské Beskydy Mts. and Podbeskydská pahorkatina Uplands; however, seven of these cannot be considered part of the fauna of this area as they probably never occurred there, and one species (Perla abdominalis Burmeister, 1839) was not confirmed, despite being demonstrably recorded in 2000. In the present study, the current stonefly fauna was confirmed at 14 species, belonging to three families and eight genera. The occurrence of Isoperla sudetica (Kolenati, 1859) is published for the first time. Among the most important findings are confirmation of the occurrence of two endangered species (Perla grandis (Rambur, 1841) and Arcynopteryx dichroa (McLachlan, 1872)) and one near threatened species (Isoperla buresi Raušer, 1962). Equally important is confirmation of the occurrence of Perlodes intricatus (Pictet, 1841), based on egg morphology and DNA barcoding.

Authors: Csanády Alexander
Published: March 2022

In this study are presented six cases of abnormal behaviour based on injured individuals of Mus spicilegus from northern border of the species’ range. The material consistent of six individuals caught during autumn-winter season 2020 in field biotope on south-eastern Slovakia. Determination by morphological traits and subsequent dissection confirmed that all trapped mice were subadults. The cause of the damage found in distinctly bite was aggressive behaviour by other individuals or selfmutilation. There were three main types of damage: (1) incomplete infanticide (2) cannibalism and finally (3) self-mutilation. The findings presented in this study display the first documented abnormal behaviour in the mound-building mouse obtained in the wild.

Authors: Marcelo Talita , Garcia Di João Juliano , Carvalho Góes Fernandez Gisleide
Published: March 2022

Atualmente existe uma grande preocupação em nosso sistema de saúde relacionado a superlotação dos serviços de urgência, tal fato tem ocorrido pelo aumento da demanda de pacientes com queixas leves, no qual se deve direcionar a atenção básica. Os objetivos desse estudo são compreender através da revisão bibliográfica os reais motivos da superlotação nas Unidades de Pronto Atendimento (UPA) e identificar a demanda clínica do setor com os casos de baixa gravidade segundo o protocolo de Manchester pelo quais poderiam ser resolvidos no âmbito de Atenção Primária à Saúde (APS). Tratou-se de uma revisão bibliográfica, do tipo exploratório-descritivo quantitativo. Na pesquisa foram coletados relatos de estudos direcionados na compreensão da superlotação das UPA’s e o perfil de seus usuários publicadas nos últimos 10 anos. Os resultados obtidos foram dezenove publicações divididas em três categorias: acessibilidade à atenção básica; enfermagem frente ao acolhimento e classificação de risco; perfil dos usuários do serviço de saúde. As publicações evidenciaram que a superlotação de um pronto atendimento se dá pela busca do imediatismo do usuário e pelo acolhimento recebido pelos profissionais da saúde, causando essa dificuldade na atenção básica, por falta de infraestrutura, organização dos serviços, ausência de reconhecimento de demandas prioritárias, baixa resolutividade em ações de saúde. Conclui-se que há falta de conhecimento em educação em saúde da população usuária do sistema e também fragilidades da atenção primária causando baixa confiabilidade dos usuários o que leva a superlotação das UPA’s.

Langerhans cell histiocytosis (HCL) is a mainly pediatric disease whose severity is highly variable and clinical presentation depends on the site affected. Excluding craniofacial lesions, the spine is the most frequently involved bone site. A 5-year-old male, admitted to a tertiary hospital with a history of three weeks of low back pain, with irradiation of lower limb pain, which made walking difficult, with partial improvement after the use of anti-inflammatories. He denied traumas, fever or other symptoms during the period. On physical examination, he presented pain on palpation of the lumbar region, absence of skin lesions or other alterations. Previous HIV diag-nosis by vertical transmission, in irregular use of antiretroviral therapy (zidovudine, lamivudine, lopinavir, and ritonavir), with CD4+ cell count of 314/mm3 (12%) and viral load of 28,937 copies (log 4.46). Upon admission, he had normal blood count and high inflammatory activity tests. Computed tomography of the thoracolumbar spine showed destructive lesions of vertebral bodies of T4, T8, and L1. Patient was then submitted to vertebral biopsy, with anatomopatho-logical examination of the tissue, receiving the diagnosis of HCL. In the isolated sample of bone tissue, culture for bacteria and fungi and PCR for tuberculosis were negative. HCL is a disease of difficult suspicion and diagnosis, since its low incidence and nonspecific symptoms, common to many pathologies. For the described patient, HIV infection with high viral load and low concen-tration of CD4+ lymphocytes made the diagnosis even more challenging.

Published: March 2022

Chemical food preservation is the common strategy used by human to preserve the natural properties and to increase the shelf life of food. Although preservatives are useful to keep the food fresh and to stop the bacterial growth, there are certain preservatives that are harmful if taken in more than the prescribed limits. Some of the typical usedâ€”benzoic acid, methylparaben, and n-butylparabenâ€”were employed in this work with the aim of establishing a simultaneous liquid chromatography (LC) method for detecting each in soy sauce matrices. Liquid and C18 solid phase extraction were performed in this procedure prior to LC using Diode Array Detector analysis. In gradient elution of a format buffer (pH 4.4) and acidified acetonitrile, the target components were successfully separated. Calibration curve ranged from 0.61â€“140 mg/kg linearly while the limit of quantification for benzoic acid, methylparaben, and n-butylparaben were 0.41, 0.10, and 0.11 mg/kg, respectively. The intermediate precision and recovery were in the range between 0.15-1.89% and 100.5-103.3%, respectively. The expanded uncertainty (k=2) in sample measurement was estimated at 3.4-6.5%. The offered method was conformed to the validation acceptance criteria and can be applied as a routine method in the laboratory at ppm level.
Generating Sympathy for Specific Characters and Events in Mandla Langa’s

The Dead Men Who Lost Their Bones(1996)
Authors: Sibuyi Dzunisani
Published: March 2022

In this article, I investigate MandlaLanga’s short story,
The Dead Men Who Lost Their Bones, by applying GérardGenette’s
Narrative Discourse and
Narrative Discourse Revisited along with MikhailBakhtin’s
Dialogic Imagination to the text. By highlighting the way in which Langa employs narrational strategies to generate meaning in the story, I aim to correct the critical neglect of this aspect of his work. It is established that two narrational modes– intradiegetic–homodiegetic and intradiegetic–metadiegetic– are employed by two central characters in the narrative. The first character narrator is Clementine, the daughter of the second narrator, SimeonNgozi. This produces a heterodiegetic narrative, that is, a multiple narrative strategy. This multi-voiced polyphonic narrative accentuates the plight of the main characters and their struggles under oppressive and exploitive conditions in apartheid South Africa. It also generates sympathy for these events as well as for Clementine and her father.

Published: March 2022

The article is dedicated to the main aspects of recreational forest management in Ukraine. According to epidemiological situation in the country, one of the most important functions of the forest is recreation, because the last one, in the author's opinion, is one of the important forms of rational leisure, meaningful leisure, health and treatment, cognitive interests. The article considers the issues of general and special recreational forest use and defines the concept of "ecotourism", which means the type of tourism, that consists of travel to natural areas to satisfy cultural, environmental, educational, cognitive and other needs without anthropogenic impact (or minimal impact) on the relevant area. It is established that the constantly growing process of attracting more and more people to the cycle of recreational activities leads to the constant expansion of forest areas, to some extent covered by recreational activities. That is why an important condition for rational use, protection and management of recreational forests is their zoning. It is concluded that according to their functional features, human recreational activities in forests can be divided into the following types: medical, health, sports, tourism, cognitive, mining, emotional and motivating. And, most often, these activities are closely interrelated, or one activity stems from another. In addition, it is given the definition of "recreational forest use" - as a set of actions aimed at meeting their needs with the involvement of forest resources (recreation, tourism, sports, amateur fishing, treatment and rehabilitation, etc.).
