Treatment of Kynol fiber materials – Part 1: dyeing processes
Authors: Wang Juan , Mahltig Boris
Published: March 2022

Kynol fibers are excellent flame-retardant materials used for manifold applications. These fibers exhibit originally an orange coloration. Up to now, dyeing processes for Kynol fibers are less reported, and the functionalization of these fibers by finishing processes is less investigated. With this background, the main aim of this paper is the evaluation of different dyeing processes for Kynol fiber materials – a woven fabric and a non-woven material. The following types of dyestuff are evaluated – direct dyes, vat dyes, disperse dyes and color pigments. The reached color quality is determined by CIE L*a*b* indices. Dry and wet rubbing fastness is measured. Finally, best results are gained by application of disperse dyes. The gained results could be used in future also to develop other functional treatments of Kynol fibers in different fields for, e.g., light protection, UV-stability, water repellency or antistatic properties.
El “caballero de frontera” en The Mandalorian (Disney+ 2019-2020)
Authors: Gutiérrez Delgado Ruth
Published: March 2022

En este artículo propongo el concepto de caballero de frontera para definir el prototipo heroico que surge de la conversión de dos géneros narrativos: el space-western y la fantasía épica o heroica. Este concepto se aporta tras la re-visitación del héroe de frontera en la serie The Mandalorian (Disney+, 2019-2020), de acuerdo con algunos rasgos propios del concepto medieval de caballero andante. El arquetipo del héroe de frontera  se adscribe al subgénero de space-western, donde recibe su condición de outlaw; sin embargo, gracias a los elementos de fantasía épica que hereda de su pertenencia al universo de Star Wars, el héroe sufre una transformación paulatina en el desenvolvimiento de su misión que lo acerca al caballero andante. Por ello, el objetivo de este artículo es doble: por un lado, categorizar ese arquetipo heroico surgido de la combinación de dos géneros cuyas narrativas presentan semejanzas a través de la figura del outsider como protagonista. Por otro lado, para tal objetivo, se explora una metodología mixta entre la semiótica y la hermenéutica en la cual se aplican los conceptos de desplazamiento metafórico y de relación por semejanza.

Authors: Londoño-Proaño Cristián
Published: March 2022

La transformación digital generó cambios vertiginosos e importantes en la industria de los medios. Hay saturación de contenido y variación en el patrón de consumo. Los públicos migraron de los medios tradicionales a los digitales. Varios fueron vendidos, mientras que otros se fusionaron. Cada día se insertan nuevos actores, que aumentan la competencia de los medios. El liderazgo, la innovación y la creatividad son algunas de las alternativas que los medios pueden utilizar para aprovechar las oportunidades y volverse competitivos. El liderazgo transformacional es un estilo empleado en el sector de la industria de la comunicación, por el mismo hecho que en la sala de redacción (o producción) se necesita que los líderes tengan un comportamiento que favorezca la creatividad y la innovación, para ser más competitivos. En esta investigación se utiliza el Multifactor Leadership Questionnaire - MLQ- 5X, que es una herramienta ampliamente utilizada para medir el liderazgo. Se logra establecer que, en los medios públicos, el liderazgo transformacional es el estilo predominante, que hay una correlación considerable y positiva entre la influencia idealizada conductual, la estimulación intelectual y la motivación e inspiración con la satisfacción y la efectividad. Los profesionales de la comunicación de los medios públicos perciben que los directores, jefes, y coordinadores son líderes que motivan e inspiran a cumplir las metas, incluso ellos puedan dar más de ellos mismos, gracias a su compromiso y confianza.

Authors: Andini Mandira  , Chrismis Novalinda Ginting  , Linda Chiuman
Published: March 2022

The toxic and carcinogenic effects of benzene are caused by several factors such as the duration, mode and level of exposure, and individual susceptibility factors (age, gender, lifestyle, and pre-existing diseases). Syzygium polyanthum (Wight) Walp, known as the bay leaf, is a species of the Myrtaceae family. It is used as traditional medicine by various ethnic groups, especially in Southeast Asia, such as Malaysia and Indonesia. This study aimed to determine the neuroprotective effect of the ethanolic extract of Syzygium polyanthum using 44 rats. These experimental animals were divided into eleven groups, each consisting of 4 rats. The normal group was given only CMC (carboxymethyl cellulose), while negative 1 and 2 were given benzene 100 mg/kg BW every 6 and 3 days intraperitoneally. Furthermore, positive groups 1 and 2 were treated with vitamin c + benzene 100 mg/kgbw every 6 and 3 days, respectively. Group I-6 rats were given the extract at a dose of 400, 600, and 4800 mg/kgbw + benzene 100 mg/kgbw every 3 and 6 days during 21 days of the experiment. On day 22, the rats were injected with 1% ketamine and their blood samples were taken directly from the heart. This was followed by Interferon Gamma and COX-2. The result showed that the ethanolic extract of Syzygium polyanthum can reduce the biomarker of Interferon-gamma and COX-2 in benzene-induced rats.

Authors: Atarchi Zaid R , Miley D Douglas , Atarchi Ahmed R
Published: March 2022

Background: To assess the alveolar bone crest level (ABCL) by Cone Beam Computed To-mography (CBCT) and to investigate several variables as predictors for the height of the alveolar bone in adolescents. Materials and methods: Age, sex, and ethnic groups were rec-orded for each patient. CBCT images were used to obtain measurements of the interproximal alveolar bone level from the cementoenamel junction (CEJ) to the alveolar crest. The highest measurement in each sextant was recorded along with any presence of a vertical bone defect or calculus. Results: Total of 720 measurements were recorded for 120 subjects. No vertical bony defects or calculus were observed radiographically. Statistically significant (P< 0.05) differences were observed between ABCL measurements of males as compared to females, posterior teeth compared to anterior teeth and maxillary sextants in comparison to man-dibular ones. Additionally, value of ABCL significantly increased in relation to sex (r=0.309), maxillary posterior (r=0.509) and mandibular posterior sextants (r=0.506). Linear regression analysis indicated that the latter variables can predict the height of marginal bone, other independent variables were considered redundant. Conclusions: There was a low-profile of marginal bone loss among adolescents. Male sex, posterior teeth, and maxillary teeth have higher tendency for decreasing alveolar bone height.

Authors: Al-Mamoori Reem Majeed H.J. , Al Haidar Aseel Haidar M.J.
Published: March 2022

Background: White spot lesion is the first visible sign of dental caries that is characterized by demineralized lesion underneath an intact surface. Several studies demonstrated that they could be treated using noninvasive techniques like the use of fluoride or casein phospho-peptide and amorphous calcium phosphate. Improvement in aesthetic outcomes by covering the demineralized enamel is one of the advantages of the use of resin infiltration and opal-ustre microabrasion, which are two new techniques that had been used for treatment of white spot lesion. The purpose of this study was to evaluate the impact of resin infiltration and microabrasion in the microhardness of the artificial white spot lesions at various depths. Material and method: Forty-eight artificially white spot lesions were divided into three groups (n=16) according to the depth of the lesion (shallow enamel, deep enamel, shallow dentine). Then, each of the main groups was divided into two subgroups (n = 8), the first group was treated with resin infiltration, while the second one was treated with Opalustre microabrasion. Assessment of the microhardness was done using Vickers hardness at the baseline, after demineralization (formation of the white spot lesion) and after the treatment with the resin infiltration and the microabrasion. Results: There was a significant difference in the microhardness of all the layers after demineralization. Although the hardness values that found among the icon group in the inner enamel and the outer dentine were higher than that of the opalustre, statistically there was no significant difference between the two mate-rials in all the layers of the white spot lesion. Conclusion: Microhardness values decrease as the depth of the white spot lesion increase. There was an increase in the microhardness values after the treatment with the resin infiltration and the microabrasion.

Pembelajaran biologi memerlukan pemahaman konsep yang benar. Konsep yang diajarkan secara benar akan membantu siswa memperoleh pengalaman belajar yang tepat dan terhindar dari miskonsepsi. Miskonsepsi merupakan suatu persepsi yang salah terhadap suatu konsep yang dimiliki oleh siswa yang tidak sesuai dengan konsepsi ilmiah. Miskonsepsi masih sering terjadi pada materi Biologi, salah satunya pada materi Sistem Gerak Manusia. Tujuan penelitian ini untuk mendeskripsikan profil miskonsepsi siswa pada materi Sistem Gerak Manusia dan mengetahui faktor penyebab miskonsepsi. Penelitian ini termasuk penelitian deskriptif. Metode penelitian ini dengan menggunakan teknik four-tier true false diagnostik test dengan pengambilan data yang dilakukan secara online melalui google form. Sasaran penelitian ini siswa SMA Negeri 1 Tarik kelas XI MIPA 7 sebanyak 35 siswa. Hasil penelitian menunjukkan profil miskonsepsi siswa pada materi Sistem Gerak Manusia sebesar 26%. Miskonsepsi tertinggi pada konsep kontraksi otot yaitu sebesar 38% dan miskonsepsi terendah pada konsep tulang sebesar 10%. Kategori miskonsepsi tergolong kategori rendah. Faktor penyebab miskonsepsi berasal dari siswa yang memperoleh keyakinan konsep sendiri pada beberapa konsep materi Sistem Gerak Manusia yang dianggap sulit, buku teks yang digunakan tidak terperinci serta penjelasan guru yang kurang mendetail dan terlalu cepat. Tindak lanjut dari hasil penelitian ini adalah perlu diadakannya penelitian yang fokus pada pemahaman konsep yang benar dalam materi Sistem Gerak Manusia agar tidak terus-menerus pada konsep yang salah dengan lebih menekankan pada proses penyembuhan miskonsepsi pada siswa.

Abstract

Lack of conceptual comprehension can lead students to form a wrong concept. Students’ conceptual comprehension that is different from the actual concept is called a misconception. Biological topic that is prone to misconception is cell bioprocess because the topic is abstract and complete. This research aims to describe the profile of students’ misconceptions using the three-tier diagnostic test, to describe the factors that cause misconceptions, and to offer solutions that overcome students’ misconceptions in cell bioprocess topic. The data collection methods were carried out by providing a three-tier diagnostic test through google form and interviewing through google meet and social media. The research subjects were 60 students of the 11th grade MIPA in SMA Negeri 1 Kamal. The data of diagnostic test were processed and grouped according to the category of students’ conceptual comprehension, besides the interviews data were analyzed by generalizations based on interviews’ answers. The results showed that 76% misconception occurred in cell bioprocess with 79.40% misconception in membrane transport, 74.30% misconception in protein synthesis, and 71.80% misconception in cell reproduction. Factors that cause misconceptions are students' low mastery of the concepts, the use of complicated terms and incomplete information in textbooks, also the lack of interaction between teachers and students. Students’ misconceptions can be reduced through the application of interactive models or media that assist in constructing conceptual comprehension correctly. Further studies of the development and implementation of digital-based learning media in cell bioprocess topic including membrane transport, cell reproduction, and protein synthesis sub-topic should be done near the future to reduce students’ misconceptions.
